A facile synthetic approach to β,γ-unsaturated esters by deconjugative esterification of α,β-unsaturated carboxylic acids with alcohols in the presence of 1,3-dicyclohexylcarbodiimide (DCC), Me3N·HCl, and Me2NEt is described. The one-pot synthesis was effectively improved under microwave irradiation.
一种简便的合成方法,通过在1,3-二环己基
氨基
脲(
DCC)、
氯化
三甲胺(Me3N·HCl)和
二乙基氨(Me2NEt)的存在下,将α,β-不饱和
羧酸与醇进行脱共轭醇酯化,合成β,γ-不饱和酯。这种一步法合成在微波辐射下得到了有效改善。
