the Beckmann fragmentation of alpha-alkoxy and alpha-alkoxy-alpha-alkyl oxime acetates have been successfully trapped as phosphonium salts, which were subsequently reacted with a variety of Grignard reagents to give the corresponding substituted products in good yields. Notably, this reaction proceeded smoothly even from alpha-alkoxy-alpha-alkyl oxime acetates.
在贝克曼裂解α-烷氧基和α-烷氧基-α-烷基
肟肟乙酸酯过程中形成的中间体已成功捕获为phospho盐,随后与各种
格氏试剂反应以高收率得到相应的取代产物。值得注意的是,即使从α-烷氧基-α-烷基
肟肟乙酸酯,该反应也能顺利进行。
