Lundrigan, Travis published the artcileEnantioselective Imine Reduction Catalyzed by Phosphenium Ions, Recommanded Product: (S)-2-Methylpropane-2-sulfinamide, the main research area is diazophosphenium triflate cation preparation reduction catalyst; enantioselective imine reduction aryl heteroaryl pyrrolidine piperidine.
The first use of phosphenium cations in asym. catalysis is reported. A diazaphosphenium triflate, prepared in two or three steps on a multigram scale from com. available materials, catalyzes the hydroboration or hydrosilylation of cyclic imines with enantiomeric ratios of up to 97:3. Catalyst loadings are as low as 0.2 mol %. Twenty-two aryl/heteroaryl pyrrolidines and piperidines were prepared using this method. Imines containing functional groups such as thiophenes or pyridyl rings that can challenge transition-metal catalysts were reduced employing these systems.
Journal of the American Chemical Society published new progress about Crystal structure. 343338-28-3 belongs to class amides-buliding-blocks, name is (S)-2-Methylpropane-2-sulfinamide, and the molecular formula is C4H11NOS, Recommanded Product: (S)-2-Methylpropane-2-sulfinamide.
