摘要

1 烷基-3-苯基丙-2-炔-1-酮在三苯基膦存在下（乙腈，室温，24 小时）与芳香醛顺利发生反应，从而以区域和立体选择性方式得到 (Z)-2-亚苄基氧杂环戊烷-3-酮，收率高达 93%。所提出的转化机理涉及中间体 β-磷酰乙烯基烷基的 1,3-H 质子转移。

The reaction of 1-alkyl-3-phenylpropynones with aromatic aldehydes: an update

1-Alkyl-3-phenylprop-2-yn-1-ones smoothly react with aromatic aldehydes in the presence of triphenylphosphine (acetonitrile, room temperature, 24 h) to regio- and stereo- selectively afford (Z)-2-benzylideneoxacyclopentan-3-ones in yields up to 93%. The proposed mechanism for the transformation involves 1,3-H proton shift from the alkyl group at the intermediate β-phosphoniovinylide species.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
