One-step synthesis of N-protected glycosylamines from sugar hemiacetals
摘要:
Protected pentofuranose, hexofuranose and hexopyranose hemiacetals were found to react efficiently with amines carrying a deactivating group (alkoxycarbonyl, tosyl or phosphoryl group) in the presence of a Lewis acid to give the corresponding, stable glycosylamines. Such glycosylamine derivatives are useful substrates for further elaboration into nitrogen-containing natural products and carbohydrate mimetics. (C) 2007 Elsevier Ltd. All rights reserved.
