Efficient and single pot process for the preparation of enantiomerically pure solifenacin succinate, an antimuscarinic agent

The development of an efficient and economic one-pot process, in which the configuration of the chiral centers of the starting materials is retained, for the preparation of highly pure solifenacin succinate, an antimuscarinic agent, is presented in this communication. The earlier reported processes suffer from the drawbacks of racemization and low yields due to the use of strong base, higher temperatures, and longer reaction times. The present work circumvents these issues by activating (3R)-quinuclidin-3-ol into a mixed active carbonate derivative by treating it with bis(4-nitrophenyl)carbonate. The subsequent reaction of the active carbonate with an enantiomerically pure amine without using any base at ambient temperature provided enantiomerically pure solifenacin with an overall yield of 90%.

Identification of an Imine Reductase for Asymmetric Reduction of Bulky Dihydroisoquinolines

A new imine reductase from Stackebrandtia nassauensis (SnIR) was identified, which displayed over 25- to 1400-fold greater catalytic efficiency for 1-methyl-3,4-dihydroisoquinoline (1-Me DHIQ) compared to other imine reductases reported. Subsequently, an efficient SnIR-catalyzed process was developed by simply optimizing the amount of cosolvent, and up to 15 g L-1 1-Me DHIQ was converted completely without a feeding strategy. Furthermore, the reaction proceeded well for a panel of dihydroisoquinolines, affording the corresponding tetrahydroisoquinolines (mostly in S-configuration) in good yields (up to 81%) and with moderate to excellent enantioselectivities (up to 99% ee).

Enantioselective and rapid Rh-catalyzed arylation of N -tosyl- and N -nosylaldimines in methanol

Enantiomerically enriched tosyl-protected diarylmethylamines were rapidly prepared by the asymmetric addition of arylboronic acids to N-tosylaldimines under mild conditions in the presence of a catalyst prepared in situ from Rh(I) and a chiral diene ligand. This methodology offers access to diarylmethylamines in good yields with excellent chiral purity at room temperature using MeOH as a solvent and NEt3 as a base. Its synthetic utility was demonstrated by the preparation of (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline (14), an antagonist of the N-methyl-d-aspartate (NMDA) receptor.

Iodo-Bodipys as visible-light-absorbing dual-functional photoredox catalysts for preparation of highly functionalized organic compounds by formation of C-C bonds via reductive and oxidative quenching catalytic mechanisms

Iodo-Bodipys were used as organic catalysts for three different photoredox catalytic organic reactions, i.e. the aza-Henry reaction of tetrahydroisoquinoline, oxidation/[3 + 2] cycloaddition/oxidative aromatization tandem reaction between tetrahydroisoquinolines and maleimides, and C-H arylation of heteroarenes with diazonium salts. The organic photocatalysts act as either electron acceptors (reductive quenching) or electron donors (oxidative quenching) in the single electron transfer (SET) of the catalytic cycles. Different from the widely used Ru(bpy)3[PF6]2, Ir(ppy)3, or halo-xanthane photocatalysts (Eosin Y or Rose Bengal), the new organic photocatalysts show strong absorption of visible light and long-lived triplet excited states, which are beneficial for SET, a crucial step for photoredox catalytic organic reactions. Moreover, the molecular structures of the new photocatalysts can be easily modified, as a result the absorption wavelength of the photocatalysts was readily tuned from 529 nm to 630 nm. The three different types of organic reactions are accelerated with the new organic photocatalysts (typical reaction times 1-2 h) compared to that catalyzed by Ru(bpy)3[PF6]2 or Ir(ppy)3 (reaction time: 12-72 h). The C-H arylation of thiophene with phenyl diazonium salts was used to prepare new Bodipy derivatives that show large Stokes shift. Our results are useful for designing of new organic catalysts for photoredox catalytic organic reactions to prepare highly functionalize organic compounds.
