Catalytic enantioselective one-pot approach to cis- and trans-2,3-diaryl substituted 1,5-benzothiazepines

The first enantioselective catalytic approach to cis- and trans-2,3-diaryl substituted 1,5-benzothiazepines has been conveniently developed in a one-pot fashion, starting from α,β-unsaturated acyl pyrazoles and 2-aminothiophenol. The organocatalytic two-s

Multifunctional Photoadditions of Stilbene to Derivatives of Caffeine and Benzothiazole

Electronically excited stilbene (1*) is trapped by 8-substituted caffeine derivatives (2a-f) or 2-chloro- (14) and 2-aminobenzothiazole (21) with variable results.While the electron-rich systems (2c,d) produce mostly propellanes, the halogeno compounds 2a,b and 14 react predominantly via insertion into the C-halogen bond.With 14 there occurs also some C-S insertion, with 21 only N-H insertion.Numerous succeeding reactions are elucidated and the reaction mechanisms discussed.Stilbene (1) photoadds hydrogen chloride to yield 16.
