Comparative molecular field analysis (CoMFA) models of phenylethanolamine N-methyltransferase (PNMT) and the alpha2-adrenoceptor: The development of new, highly selective inhibitors of PNMT

As a guide to the development of new and more selective inhibitors of phenylethanolamine N-methyltransferase (PNMT) vs the alpha2-adrenoceptor, we have performed a comparative molecular field analysis (CoMFA) on a series of 80 benzylamine analogues. Using the models obtained, we have proposed a series of 3-trifluoromethyl-1,2,3,4-tetrahydroisoquinolines and predicted the activity of other analogues.

Reactions Catalysed by a Binuclear Copper Complex: Aerobic Cross Dehydrogenative Coupling of N-Aryl Tetrahydroisoquinolines

Binuclear copper complex [{Cu(Sal)2(NCMe)}2] (Sal=salicylate) was found to be an active catalyst for the aerobic oxidation of N-aryl tetrahydroisoquinolines to the corresponding iminium ions, which could be trapped by a wide range of nucleophiles to form coupled products. The reactions took place under 1 bar of O2 at room temperature with 1 mol % of the copper catalyst being sufficient in most cases, and are considerably accelerated by catalytic chloride anions. Mechanistic studies show that the CuII dimer oxidizes the amine to the iminium ion, and this two-electron process requires O2, whereby the resulting CuI is concomitantly reoxidised back to CuII. Various lines of evidence suggest that the oxidative coupling reaction is turnover-limited by the step of iminium formation, and it is this step that is promoted by the chloride anion. Since it is more efficient than and mechanistically distinct from the well-studied simple copper salts such as CuBr and CuCl2, the binuclear copper catalyst provides a new tool for oxidative coupling reactions.

Inhibitors of phenylethanolamine N-methyltransferase and epinephrine biosynthesis: I. Chloro-substituted 1,2,3,4-tetrahydroisoquinolines

In a search for inhibitors of epinephrine biosynthesis as potential therapeutic agents, a series of 13 ring-chlorinated 1,2,3,4-tetrahydroisoquinolines was prepared. These compounds were tested initially for their ability to inhibit rabbit adrenal phenylethanolamine N-methyltransferase (PNMT) in vitro. Enzyme-inhibitor dissociation constants, determined for the six most potent members of the series, indicated the following order of decreasing potency: 7,8-Cl2>6,7,8-Cl3>7-Cl~8-Cl>5,6,7,8-Cl4>5,7,8-Cl3. These compounds were subsequently examined for PNMT-inhibiting activity in intact rats and mice. 7,8-Dichloro-1,2,3,4-tetrahydroisoquinoline (SK&F 64139) was the most potent member of the series both in vitro and in vivo and is currently undergoing clinical investigation.

Gold(III)-catalyzed enynamine-cyclopentadiene cycloisomerization with chirality transfer: An experimental and theoretical study indicating involvement of dual au(iii) push-pull assisted cis – Trans isomerism

A synthetic approach for asymmetric ring-fused cyclopentadienes (Cps) with a chiral carbon at the ring junction has been established from chiral enynamines by achiral Au(III) catalysis. On the basis of experimental and theoretical data, the proposed mechanistic pathway from enynamines to Cps occurs via a Au(III) ene cis-trans isomerization step. Computational studies at DFT and NEVPT2 levels advocate that the cis-trans isomerization step proceeds via a dual Au(III) push-pull assisted intermediate with a low computed rotation barrier. The chirality transfer occurs through a helical-shaped transition state with allenic character. The scope of the catalysis encompasses sterically bulky enynamines including terpene natural products.

Recent progress in asymmetric catalysis and chromatographic separation by chiral metal?organic frameworks

Metal?organic frameworks (MOFs), as a new class of porous solid materials, have emerged and their study has established itself very quickly into a productive research field. This short review recaps the recent advancement of chiral MOFs. Here, we present simple, well-ordered instances to classify the mode of synthesis of chiral MOFs, and later demonstrate the potential applications of chiral MOFs in heterogeneous asymmetric catalysis and enantioselective separation. The asymmetric catalysis sections are subdivided based on the types of reactions that have been successfully carried out recently by chiral MOFs. In the part on enantioselective separation, we present the potentiality of chiral MOFs as a stationary phase for high-performance liquid chromatography (HPLC) and high-resolution gas chromatography (GC) by considering fruitful examples from current research work. We anticipate that this review will provide interest to researchers to design new homochiral MOFs with even greater complexity and effort to execute their potential functions in several fields, such as asymmetric catalysis, enantiomer separation, and chiral recognition.
