of regioisomerically pure aminodeoxy sugars (6)–(11) has been achieved by trans-diaxial cleavage of the oxirane ring in 2,3-anhydro sugars (1)–(5) with N,N-diethyltrimethylsilylamine or its N,N-dimethyl analogue, using AlCl3 as catalyst; the reagents work under mild conditions and avoid the difficulties which sometimes are encountered in ring-opening reactions of epoxy sugars.
通过N,N-二乙基三甲基甲硅烷基胺在2,3-脱水糖(1)–(5)中环氧乙烷环的反式双轴裂解,已实现了一种区域异构纯氨基脱氧糖(6)–(11)的新型一步合成。或其Al,N-N-二甲基类似物,使用AlCl 3作为催化剂;该试剂在温和的条件下工作,避免了环氧糖开环反应中有时遇到的困难。
