Novel carbohydrate-derived pyridinecarboxylic organocatalysts for the enantioselective reduction of imines with trichlorosilane
摘要:
A new type of carbohydrate-derived pyridinecarboxylic organocatalyst was prepared by fine-tuning a D-glucosamine backbone at the C-2 and C-3 positions. The carbohydrate-derived pyridinecarboxylic organocatalyst was used for the enantioselective reduction of imines with trichlorosilane. The reduction proceeded in high yield (up to 93%) and with moderate enantioselectivity (up to 75%). (C) 2014 Elsevier Ltd. All rights reserved.
