• Study on the Reactions of Acetylenic Aldehydes with Dimethyl Phosphite in Basic Media: Phosphonate-Phosphate Rearrangement<i>versus</i>5-<i>exo</i>-dig Cyclization Reactions

  日期：2012.10.8

  Tandem reactions of various acetylenic aldehydes with dimethyl phosphite in basic media were investigated. It was shown that in the case of a non-activated triple bond of the starting materials, the well-known Pudovik reaction followed by a subsequent phosphonate-phosphate rearrangement took place. On the other hand when the triple bond of the starting materials is activated by electron-withdrawing

  在碱性介质中研究了各种炔醛与亚磷酸二甲酯的串联反应。已经表明，在起始材料的未活化的三键的情况下，发生了众所周知的Pudovik反应，随后发生了膦酸酯-磷酸盐的重排。另一方面，当起始材料的三键被吸电子杂环激活时，顺畅且区域选择性的串联5-外切-环化反应成为可能。
