Reactions of 3- -acetyl-2- - -tolylsulfonyl-D- - and - - -hex-1-enitol derivatives with nucleophiles; the SN2′ mechanism is proved firstly in glycal derivatives
Reactions of the title compounds with sodium methoxide and sodium borodeuteride were found to proceed mainly via the SN2′ mechanism; nucleophiles selectively attacked the anomeric carbon atom from the same side of the leaving acetoxyl group at -3.
发现标题化合物与甲醇钠和硼氢化钠的反应主要通过S N 2'机理进行。亲核试剂从-3处剩下的乙酰氧基基团的同一侧选择性攻击异头碳原子。
