Enantioselective reductions of 2-acyl-1,3-dithianes using the corey oxazaborolidine catalyst
摘要:
The enantioselective reduction of acyl dithianes has been achieved using the oxazaborolidine catalyst 1b. The dithiane group can then be hydrolyzed to the ketone or removed reductively.
The anodicoxidation of α-keto and α-hydroxythloacetals provides an efficient way for the regeneration of α-diones and α-ketols, specially in the cases where chemical reactions are unsuccessful.
