An effective imide formation method is presented, which allows the preparation of β,γ-unsaturated N-acyl-2-oxazolidinones with high yields and without isomerization of the double bond to give the α,β-unsaturated isomers, which are the inevitable by-products when alternative procedures are used.
提出了一种有效的
酰亚胺形成方法,该方法可以高产率地制备β,γ-不饱和N-酰基-2-
恶唑烷酮,且不发生双键异构化而得到α,β-不饱和异构体,这是不可避免的。使用替代程序时的产品。
