摘要
α-溴代醛是一种有用的有机合成中间体,主要用于制备α、β-不饱和醛和定向合成的光学活性异构体.本文从易得的原料开始,制备一种使用方便的溴化剂-二溴麦尔多姆酸,使脂肪醛发生α-溴化反应不仅条件温和、操作简便,而且收率高,后处理方便.所合成的一系列α-溴代醛经沸点.1HNMR和GC—MS所确证.
In organic synthesis α-bromoaldehydes are important media, which can be used to prepare α,β-unsaturated aldehydes and to stereoselectively synthesize a convenient bromizing agent-Dibromo Meldrum'sAcid (5, 5 -dibromo- 2, 2 - dimethyl - 4, 6 - dioxo - 1. 3 - dioxane), making the α-bromizating reaction ofalkyl aldehydes not only easily operated and conveniently postdealt with, but also in mild condition and ingood yield.The structues of α-bromoaldehydes were confirmed by boiling point, 1H NMR and GC-MSspectra.
