2-二甲氨基吡啶催化合成2H-吡喃类化合物
|
Abstract:
本文以2-二甲氨基吡啶作为一种有机催化剂，催化α-溴代肉桂醛、1,3-二羰基化合物在二氯甲烷中反应合成了一系列2H-吡喃类化合物。该方法具有环境友好、操作简单的特点。
In this paper, a series of 2H-pyrane compounds were synthesized by the reaction of α-bromocinna- maldehydes with 1,3-dicarbonyl compounds in dichloromethane using 2-dimethylaminopyridine as an organic catalyst. The method is environment friendly and easy to operate.
