Crystallographic/experimental electron density characterizations and reactions with nucleophiles of beta-enaminonitriles possessing a pyrrolobenzazepine core

In connection with a total synthesis of cephalotaxine (1a), we have examined the addition of various nucleophilic reagents to [ABC] subunits 2 and 7 possessing a pyrrolobenzazepine core. In fact, this reaction implicates invariably the carbonyl group of 2. Regarding the reaction of 7 with nucleophiles, the most striking aspect is the complete lack of reactivity of the enaminonitrile moiety. For instance, the condensation of 7 with methylmagnesium bromide involves exclusively the cleavage of the dioxole ring, yielding regioisomers 9 and 10. With the aim of understanding the unexpected reactivity of 2 and 7 toward nucleophiles, crystallographic studies of 2 and 7 and an experimental electron density determination of 7 were carried out. The marked reactivity of the carbonyl group of 2 was interpreted by invoking the weakness of the amide resonance, due to a pronounced delocalization of the N-9 lone pair over the enaminonitrile moiety. The electron density study of 7 reveals this electron delocalization along the enaminonitrile fragment, highlighted and quantified through the bond geometries, topological indicators, and atomic charges, a phenomenon that is responsible for the failure of the addition of nucleophilic species.

SYNTHESIS AND PHARMACOLOGICAL EXAMINATION OF BENZOFURAN, INDAN, AND TETRALIN ANALOGS OF 3,4-(METHYLENEDIOXY)AMPHETAMINE

Benzofuran, indan and tetrahydrohaphthalene analogs of 3,4-(methylenedioxy)amphetamine (MDA) were prepared in order to examine the role of the dioxole ring oxygen atoms of MDA in interacting with the serotonin and catecholamine uptake carriers. The series of compounds was evaluated for discriminative stimulus effects in rats trained to discriminate saline from the training drugs (S)-(+)-MBDB (1c), MMAI (3), and (S)-(+)-amphetamine and for the ability to inhibit the uptake of [H-3]serotonin, [H-3]dopamine, and [H-3]norepinephrine into crude synaptosome preparations. Behaviorally, the benzofuran and indan analogs 4-6 produced similar discriminative cues, whereas the tetralin derivative 7 did not fully substitute for the training drugs. The results in the in vitro pharmacology studies indicate that selectivity for 5-HT versus catecholamine uptake carriers may be modulated by the position and orientation of ring oxygen atoms. However, the nonoxygenated isostere 6 possessed high potency at all uptake sites examined. Enlargement of the saturated ring by one methylene unit to give the tetralin derivative resulted in a large (3-4-fold) reduction in activity at catecholamine sites.

Performance of a composite membrane of a perfluorodioxole copolymer in organic solvent nanofiltration

Solvent swelling of polymers is of major importance in organic solvent nanofiltration (OSN) affecting membrane rejection of 200-1000 + Da solutes. A selected perfluoro type amorphous glassy copolymer, perfluoro-2,2-dimethyl-1,3-dioxole copolymerized with tetrafluoroethylene (PDD-TFE), is completely insoluble in all solvents except perflourinated solvents; further it showed very little swelling in solvents that are not of the perfluorinated type. Pure component permeation flux for a particular variety of this copolymer, CMS-7, was measured with a wide variety of solvents for two membrane thicknesses, 1.67 in and 0.6 pm, in a composite form supported on a porous ePTFE substrate. The feed pressure range was 1000-3000 kPa. The solvents included methanol, ethanol, ethyl acetate, n-heptane, tetrahydrofuran (THF), toluene, dimethylsulfoxide (DMSO); n-heptane showed much higher flux than the rest. Successful OSN was demonstrated with high solute rejection in methanol solutions of two dye solutes Safranin 0 (MW, 351 Da) and Brilliant Blue R (MW, 826 Da). Rejection for Safranin 0 varied between 94% and 97% depending on the pressure and membrane thickness; that for Brilliant Blue R varied in the range of 97-99.8%. Successful OSN was also demonstrated with Safranin 0 in THF with solute rejection varying between 94% and 97%. Permeation behaviors of various mixtures of two solvents, toluene and n-heptane, were studied. The measured values of very limited extent of sorption of a variety of organic solvents in 25 pm thick dense samples of this and a related perfluoro type copolymer, CMS-3, were employed to explain the observed behavior.

Fluorous Polymeric Membranes for Ionophore-Based Ion-Selective Potentiometry: How Inert Is Teflon AF?

Fluorous media are the least polar and polarizable condensed phases known. Their use as membrane materials considerably increases the selectivity and robustness of ion-selective electrodes (ISEs). In this research, a fluorous amorphous perfluoropolymer was used for the first time as a matrix for an ISE membrane. Electrodes for pH measurements with membranes composed of poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole]-co-poly(tetrafluoroethylene) (87% dioxole monomer content; known as Teflon AF2400) as polymer matrix, a linear perfluorooligoether as plasticizer, sodium tetrakis[3,5-bis(perfluorohexyl)phenyl]borate providing for ionic sites, and bis[(perfluorooctyl)propyl]-2,2,2-trifluoroethylamine as H+ ionophore were investigated. All electrodes had excellent potentiometric selectivities, showed Nernstian responses to H+ over a wide pH range, exhibited enhanced mechanical stability, and maintained their selectivity over at least 4 weeks. For membranes of low ionophore concentration, the polymer affected the sensor selectivity noticeably at polymer concentrations exceeding 15%. Also, the membrane resistance increased quite strongly at high polymer concentrations, which cannot be explained by the Mackie-Meares obstruction model. The selectivities and resistances depend on the polymer concentration because of a functional group associated with Teflon AF2400, with a concentration of one functional group per 854 monomer units of the polymer. In the fluorous environment of these membranes, this functional group binds to Na+, K+, Ca2+, and the unprotonated ionophore with binding constants of 10(3.5), 10(1.8), 10(6.8), and 10(4.4) M-1, respectively. Potentiometric and spectroscopic evidence indicates that these functional groups are COCH groups formed by the hydrolysis of carboxylic acid fluoride (COF) groups originally present in Teflon AF2400. The use of higher ionophore concentrations removes the undesirable effect of these COOH groups almost completely. Alternatively, the C(=O)F groups can be eliminated chemically, or they can be used to readily introduce new functionalities.
