Abstract
An umpolung reaction of α-tosyloximino esters in a flow system is disclosed. Tandem N,N-dialkylations with two different Grignard reagents gave the desired N,N-dialkylated products in moderate to good yields. In addition, a tandem N,N,C-trialkylation of an α-tosyloximino ester with three different Grignard reagents has been successfully achieved to afford the desired N,N,C-trialkylated product in moderate yield.

流动系统中α-Tosyloximino酯的Umpolung反应
摘要
公开了在流动系统中α-甲苯磺酰氨基酯的加速反应。用两种不同的格氏试剂串联N,N-二烷基化以中等至良好的产率得到所需的N,N-二烷基化的产物。另外,已经成功实现了用三种不同的格氏试剂对α-甲苯磺酰氨基酯进行的串联的N,N,C-三烷基化,以中等收率提供了所需的N,N,C-三烷基化的产物。
