A series of α,β-unsaturated carboxylic acid esters have been prepared by the reaction of carbonyl compounds with alkoxy acetylide anions generated in situ from the readily available α-chloroacetaldehyde dialkyl acetals in the presence of lithium diisopropylamide, followed by aqueous acidic work-up.
一系列α,β-不饱和羧酸酯是通过羰基化合物与烷氧基乙炔阴离子在二异丙基氨基锂存在下由容易获得的α-氯乙醛二烷基缩醛原位生成的反应制备的,然后进行水溶液酸性工作-向上。
