• 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

  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。

  Thermal and microwave initiated cyclization of 2,4-disubstituted 6-arylethynylpyrimidine-5-carbaldehydes with tert-butylamine has been studied. A novel high-yielding preparation of 2,4-disubstituted 7-arylpyrido[4,3-d]pyrimidines has been developed. The intermediate compounds were isolated and possible mechanism of the reactions is discussed. Crown Copyright (C) 2009 Published by Elsevier Ltd. All rights reserved.

  An efficient and versatile tandem processes of acetalisation and cycloisomerization reactions have been developed for the reactions of 6-phenylethynylpyrimidine-5-carbaldehydes. The influence of the catalyst and role of the substituent in the position 4 of the pyrimidine ring have been studied. Regioselective synthesis of 5,7-dihydrofuro[3,4-d]pyrimidine and pyrano[4,3-d]pyrimidine cores is described. (C) 2009 Elsevier Ltd. All rights reserved.
