Synthesis and Fungicidal Activity of Some Novel Thiazole Schiff Bases Derived from Benzo[d][1,3]dioxole

A series of novel thiazole Schiff base derivatives containing benzo[d][1,3] dioxole moiety was designed, synthesized and screened for their fungicidal activities. The preliminary results demonstrated that compounds 6p, 6q and 6r possessed potent activities against Phytophthora infestans, Pyricularia oryzae and Septoria tritici in vitro. Compounds 6d and 6r exhibited remarkable activities against Botrytis cinerea(whole plant) and Phytophthora infestans(leaf disk) respectively in vivo, which were identified as the most promising candidates for further study and could be used as possible lead compounds for developing new fungicides.

Anomeric Effect in Five-Membered Ring Molecules: Comparison of Theoretical Computations and Experimental Spectroscopic Results

As demonstrated in previous spectroscopic studies of 1,3-dioxole [J. Am. Chem. Soc., 1993, 115, 12132-12136] and 1,3-benzodioxole [J. Am. Chem. Soc., 1999, 121, 5056-5062], analysis of the ring-puckering potential energy function (PEF) of a pseudo-four-membered ring molecule can provide insight into understanding the magnitude of the anomeric effect. In the present study, high-level CCSD/cc-pVTZ and somewhat lower-level MP2/cc-pVTZ ab initio computations have been utilized to calculate the PEFs for 1,3-dioxole and 1,3-benzodioxole and 10 related molecules containing sulfur and selenium atoms and possessing the anomeric effect. The potential energy parameters derived for the PEFs directly provide a comparison of the relative magnitudes of the anomeric effect for molecules possessing OCO, OCS, OCSe, SCS, SCSe, and SeCSe linkages. The torsional potential energies produced by the anomeric effect for these linkages were estimated to range from 5.97 to 1.91 kcal/mol. The ab initio calculations also yielded the structural parameters, barriers to planarity, and ring-puckering angles for each of the 12 molecules studied. Based on the refined structural parameters for 1,3-dioxole and 1,3-benzodioxole, improved PEFs for these molecules were also calculated. The calculations also support the conclusion that the relatively low barrier to planarity of 1,3-benzodioxole results from competitive interactions between its benzene ring and the oxygen atom p orbitals.

Polymers based on a novel 1,3-perfluorodioxole for use as a soft polymer pellicle in 157nm lithography

A series of copolymers of tetrafluoroethylene and 4-trifluormethoxy-1,3-perfluorodioxole (TFETFMD) were prepared as well as a homopolymer of the dioxole (TEMD) using various free-radical initiators. The copolymers were characterized by F-19 NMR, TGA, DSC and VUV measurements. The transparency at 157nm increased with increasing dioxole content reaching an alpha (mum(-1)) = 0.76 for an unoptimized homopolymer of the dioxole prepared with a perfluorinated peroxide initiator. Exposure studies of the dioxole homopolymer at 157 nm indicate rapid formation of carbonyl species and therefore an anticipated short lifetime as a potential polymer pellicle for 157 nm lithography.

Benzodioxole derivatives as negative effectors of plant proteases

Previous work demonstrated that a commercial formulation of piperonyl butoxide (PBO) did inhibit the activity of some plant proteolytic enzymes. In this paper, the effect of pure PBO and nine pure PBO homologues (PBOH) appropriately synthesized toward bromelain and papain was studied in hydrocarbon solution using the bis(2-ethylhexyl)sodium sulfosuccinate (AOT) reverse micellar system. This study establishes that the majority of these compounds show, in vitro, interesting protease inhibition activities. The benzodioxole and dihydrobenzofuran structures, in particular, 5-[2-(2butoxyethoxy)ethoxymethyl]-benzo[1,3]dioxole (EN 1-40) and 6-[2-(2-butoxyethoxy)ethoxymethyl]5-propyl-2,3-dihydrobenzofuran (EN 16-5), respectively, appear to be responsible for protease inhibition. Measures of octanol/water partition coefficients on PBO and PBOH have demonstrated that water solubility plays a fundamental role in the expression of protease inhibition activity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18422-53-2 help many people in the next few years. Computed Properties of C12H18O6.

AM1 study of photoelectronic spectra .8. Direct calculations of ionization in the study of conformations of some methoxy-substituted benzenes

Ionization energies of four model compounds with known conformations, i.e., benzo-1,3-dioxole, 2-methoxyphenol, benzo-1,3-dioxole-5-carbaldehyde (piperonal), and 4-hydroxy-3-methoxybenzaldehyde, have been calculated by the ab initio AM1 method, using the formalized scheme of configuration interactions. It has been demonstrated that this method is adequate for the study of photoelectronic spectra of methoxy(hydroxy)-substituted benzenes. The ionization energies of 1,2-dimethoxybenzene, 3,4-dimethoxybenzaldehyde, and 4-hydroxy-3,5-dimethoxybenzaldehyde have been calculated for various orientations of the o-methoxy(hydroxy) groups. It has been revealed that three first ionization potentials corresponding to the states with vacancies on the pi-MO depend on the torsion angle. It has been established by comparison of calculated and experimental ionization potentials that in gas the compounds with adjacent methoxy groups have one O-Me bond parallel with the plane of the benzene ring, while another group is nearly perpendicular to this plane. Conformations of the heavy-atom framework are planar for gaseous molecules with adjacent methoxy and hydroxy groups.

Both the traditional Chinese medicinal fungus, Antrodia camphorata, and its secondary metabolite, 4,7-dimethoxy-5-methylbenzo[d][1,3]dioxole, have been reported to possess promising anticancer activity. In this work the natural product and analogues bearing more polar substituents were synthesised and assessed for antiproliferative activity in the NCI-60 screen. Although each compound inhibited the growth of some cell lines at 10 mu M, none had sufficient activity to warrant further investigation.

Chemical modification of chitosan: synthesis and biological activity of new heterocyclic chitosan derivatives

BACKGROUND: Numerous works have been published on the chemical modification of chitosan; this polymer is still being modified, leading to various derivatives with improved properties. In the present study, heterocyclic aldehydes including furan-2-carbaldehyde, 5-methylfuran-2-carbaldehyde, 3-pyridine carboxyaldehyde, benzo[d][1,3]dioxole-5-carbaldehyde and 4-oxo-4H-chromene-3-carbaldehyde were reacted with chitosan by a reductive alkylation reaction to produce for the first time five new N-heterocyclic chitosan derivatives to improve the biological activity of chitosan against the most important economic plant pests including fungi and insects, in particular the cotton leafworm Spodoptera littoralis. RESULTS: The chemical structures of the synthesized compounds were confirmed by H-1 NMR spectroscopy and the degree of substitution ranged from 0.30 to 0.43. The fungicidal assessment was investigated in vitro using a mycelia radial growth inhibition technique against soil-borne pathogenic fungi Fusarium oxysporum and Pythium debaryanum and the rice leaf blast Pyricularia grisea. The results showed that N-[(5-methylfuran-2-yl)methyl] chitosan was the most active against P. grisea with an EC50 value of 0.919mg mL(-1) while N-(benzo[d][1,3]dioxol5-ylmethyl) chitosan and N-(methyl-4H-chromen-4-one) chitosan exhibited the most potent fungicidal activity against P. debaryanum and F. oxysporum. An insecticidal bioassay against the larvae of S. littoralis showed that N-(methyl-4H-chromen-4-one) chitosan exhibited a significant growth inhibition and antifeedant activity among the synthesized compounds. CONCLUSION: The chemical modification of chitosan molecule with a heterocyclic moiety led to an enhancement in the biological activity against the plant pathogenic fungi F. oxysporum, P. debaryanum and P. grisea and the cotton leafworm insect S. littoralis.
