The generality of the addition of allenyl(cyano)cuprates to aldehydes to afford anti-1,2-disubstituted homopropargylic alcohols was studied. The reaction is general, regardless of the nature of the cyanocuprate, although with alkyl-substituted derivatives the anti selectivity is dependent upon the nature of the aldehyde.
研究了烯丙基(氰基)铜酸盐与醛加成生成反-1,2-二取代均丙炔醇的通用性。尽管烷基取代衍生物的反选择性取决于醛的性质,但无论氰基杯酸盐的性质如何,反应都是一般的。
