Abstract

Glycals have served as excellent substrates in the glycosidation reactions with arylamines to construct both C-C and C-N linkages simultaneously. However, the high reactivity and moisture/alcohol-sensitivity is also responsible for several side reactions. Herein we reported that 2,3-unsaturated glycosides can be used as alternatives of glycals to take part in the corresponding glycosidation as well. Therefore, with 10% of InBr ₃ or InI ₃ as the catalyst, 2,3-unsaturated glycosides containing various C-1 alkoxy groups reacted with arylamines smoothly and produced the glycosidation products in moderate to good yields as a pair of diastereomers with variant diastereoselectivity.
