Highly Enantioselective Arylation of N,N-Dimethylsulfamoyl-Protected Aldimines Using Simple Sulfur-Olefin Ligands: Access to Solifenacin and (S)-(+)-Cryptostyline II

With the use of a simple sulfur-olefin ligand, a highly enantioselective rhodium-catalyzed addition of arylboroxines to N,N-dimethylsulfamoyl-protected aldimines has been achieved, allowing access to a broad range of chiral diarylmethylamines in high yields (up to 98%) with uniformly excellent enantioselectivities (up to 99% ee). This catalyst system is also applicable to the arylation of N-tosyl arylimines. By utilizing this method, some biologically active molecules possessing a chiral 1-aryl-1,2,3,4-tetrahydroisoquinoline core such as Solifenacin and (S)-(+)-Cryptostyline II are facilely constructed.

An N-linked bidentate phosphoramidite ligand (N-Me-BIPAM) for rhodium-catalyzed asymmetric addition of arylboronic acids to N-sulfonylarylaldimines

A chiral N-linked C2-symmetric bidentate phosphoramidite (N-Me-BIPAM) was newly developed for the rhodium-catalyzed enantioselective addition of arylboronic acids to N-sulfonylimines. This ligand achieved high enantioselectivities in a range of

An efficient method for construction of tetrahydroisoquinoline skeleton via double cyclization process using ortho-vinylbenzaldehydes and amino alcohols: application to the synthesis of (S)-cryptostyline II

Thermal double cyclization reaction using ortho-vinylbenzaldehyde and 3-aminopropanols proceeded smoothly to give isoquinoline derivatives via 6π-azaelectrocyclization pathway. The method was applied to the efficient synthesis of (S)-cryptostyline II.
