Catechols are components of many metal-chelating compounds, including siderophores that are naturally occurring iron(III) chelators excreted by microorganisms. Catechol derivatives are poorly soluble in organic media and the synthesis of catechol-containing molecules requires the use of protected catechol precursors with improved organic solubility. We therefore developed 2,2-diphenyl-benzo[1,3]dioxole-4-carboxylic acid pentafluorophenyl ester. This activated ester reacts with an amine functionalized scaffold to generate chelators in which the catechol functions are protected in the form of diphenyl-benzodioxole moieties. The catechol can subsequently be deprotected, at the end of the synthesis, with trifluoroacetic acid (TFA). This strategy was applied to the synthesis of two catechol compounds functionalized with a terminal propargyl extension. These two compounds were shown to promote iron uptake in Escherichia coli and Pseudomonas aeruginosa. These two compounds are suitable for use as vectors in antibiotic Trojan horse approaches, as they could be conjugated with azide-functionalized antibiotics using the Huisgen dipolar 1,3-cycloaddition.

A series of 5-substituted 3-phosphonylated isoxazolidines have been obtained via cycloaddition of N-methyl-C-(diethoxyphosphoryl)nitrone with N-heteroaromatic acrylamides. Good trans/cis diastereoselectivities (d.e. 58-76%) of isomeric (3-diethoxyphosphoryl)isoxazolidines were observed. cis- and trans-Isoxazolidine phosphonates were evaluated for their antiviral activity against a broad range of DNA and RNA viruses but were found inactive. Their cytostatic activity toward L1210, CEM, and HeLa cells was also established, and compounds cis-12r and trans-11r having a 2,2-difluorobenzo[d][1,3]dioxole moiety slightly inhibited proliferation of HeLa cells at IC50 values of 186 and 179 mu M, respectively.

Methylenetriphenylphosphoranes having two phenyl groups tied together with ethano or etheno bridge were prepared by conventional ways in order to suppress delocalization of an ylide-carbanion by deforming geometrical arrangement of phenyl groups from that of the diarylmethylene derivative and hence to elevate reactivities of diarylmethylenephosphoranes. These P-ylides were, however, still unreactive with usual aldehydes and ketones. The reasons, are deliberated by molecular orbital calculations and the P-31-NMR data. The HOMO orbitals of ethano-bridged and etheno-bridged diarylmethylenephosphoranes are located on a monoarylcarbanion and a carbanion, respectively. Although these tendencies are auspicious to enhance the Wittig reactivity of them, the electron densities of the ylidic carbons are still insufficient. P-31-NMR chemical shifts of the ylides revealed that the objective P-ylides do not have a large extent of the ylide-contribution in the ylide-yllene resonance. Meanwhile, they reacted readily with tetrahalo o-quinones to give 1,3-dioxoles in good yields. Thermochromic behavior of one of the precursors, dibenzosuberenylphosphonium salt, was observed at 80 degreesC in acetonitrile in the presence of trace perchloric acid. The colored species is elucidated as dibenzo[a,e]tropylium cation.

Teflon AF 2400 (Du Pont) is an amorphous, glassy perfluorinated copolymer containing 87 mol% 2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole and 13 mol% tetrafluoroethylene. The polymer has an extremely high fractional free volume of 0.327. Permeability coefficients for helium, hydrogen, carbon dioxide, oxygen, nitrogen, methane, ethane, propane, and chlorodifluoromethane (Freon 22) were determined at temperatures from 25 to 60 degrees C and pressures from 20 to 120 psig. Permeation properties were also determined at a feed pressure of 200 psig at 25 degrees C with a 2 mol% n-butane/98 mol% methane mixture. Permeabilities of permanent gases in Teflon AF 2400 are among the highest of all known polymers; the oxygen permeability coefficient at 25 degrees C is 1600 x 10(-10) cm(3)(STP) cm/cm(2) s cmHg and the nitrogen permeability coefficient is 780 X 10(-10) cm(3)(STP) cm/cm(2) s cmHg. The permeabilities of organic vapors increase up to 20-fold as the vapor activity increases from 0.1 to unity, indicating that Teflon AF 2400 is easily plasticized. Although Teflon AF 2400 is an ultrahigh-free-volume polymer like poly(1-trimethylsilyl-1-propyne) [PTMSP], their gas permeation properties differ significantly. Teflon AF 2400 shows gas transport behavior similar to that of conventional, low-free-volume glassy polymers. PTMSP, on the other hand, acts more like a nanoporous carbon than a conventional glassy polymer.

An efficient, mild and very easy method for the synthesis of 2-fluoroalkylated 1,3-benzodioxole derivatives was developed through a double Michael-addition reaction on ethyl 4,4,4-trifluorobut-2-ynoate with corresponding catechols. The procedure does not require the use of expensive supplementary additives for the preparation of 2-fluoroalkylated benzo ketals.

Over the past few decades, numerous molecules have been discovered or designed to interact efficiently and selectively with a peculiar DNA structure named G-quadruplex. Some of these molecules have been developed as anticancer agents. To aid the design of anticancer agents, the ability of alkaloids possessing Protoberberine and Benzophenanthridine groups to induce the formation of G-quadruplexes were studied using CD spectroscopy. By careful examination of their structures, we found that a benzo[1,3]dioxole group plays an important role in influencing their inductive properties. The more functional groups the alkaloids have, the stronger their G-quadruplex inductive ability.

Membrane processes are receiving increasing attention in the scientific community and in industry because in many cases they offer a favorable alternative to processes that are not easy to achieve by conventional routes. In this context, membranes made with perfluorinated polymers are of particular interest because of the unique features demonstrated by these materials. Both highly hydrophobic and hydrophilic membranes have been developed from appropriate perfluoropolymers that were, in turn, obtained by copolymerizing TFE with special monomers available on an industrial scale. Highly hydrophobic membranes obtained from the glassy copolymers of TFE and 2,2,4-trifluoro-5 trifluoromethoxy-1,3 dioxole (Hyflon((R)) AD) exhibit properties that make them particularly well suited for use in optical applications, in the field of gas separation, and in gas-liquid contactors. Conditions for preparing membranes that are adequate for use in various applications are exemplified. Hydrophylic highly conductive proton exchange membranes obtained from the copolymer of TFE and a short-side-chain(SSC) perfluorosulfonylfluoridevinylether (Hyflon Ion) rind interesting application in the field of fuel cells, especially in view of the current tendency to move to high temperature operation. The advantages offered by these hydrophobic and hydrophylic perfluorinated materials for use in membrane technology are discussed. Comparison of membrane properties and performance is made with other membranes available on the market.

Now introduce a scientific discovery about this category.

Teflon-AF, based on the perfluoro-2,2-dimethyl-1,3-dioxole monomer (1), is a new class of high-T(g) amorphous fluoroplastics with enhanced properties over traditional fluoropolymers. New monomer and polymer chemistry that relates to fluorodioxole molecules was explored. Synthetic methods for introducing different substituents at 2-, 4-, and 5-positions of the dioxole ring were developed. The structure-property relationships of these polymers were studied, and we have found that the polymer glass transition temperatures are highly sensitive toward the structure of these monomers. The results indicated that the steric bulkiness of the substituents on the dioxole ring is critical for polymer properties, not only in the determination of glass transition temperature but also on the rate of polymerization. A rationalization is proposed to explain these observations.
