摘要

由7-羟基-4-苯基-2-[(三苯基-λ5-磷酰亚基)氨基]- 4h -3-羧酸铬与异氰酸苯酯反应得到的碳二亚胺,在乙醛存在下与不同的烷基胺和芳胺反应,得到一系列的[2,3-d]氨基-4- 1衍生物,收率较高。

Tandem Aza-Wittig/Heterocumulene-Mediated Annulation: Synthesis of Chromeno[2,3-d]pyrimidin-4-ones

Tandem Aza-Wittig/Heterocumulene-Mediated Annulation: Synthesis of Chromeno[2,3-d]pyrimidin-4-ones

The carbodiimides obtained from the reaction of ethyl 7-hydroxy-4-phenyl-2-[(triphenyl-λ5-phosphanylidene)amino]-4H-chromene-3-carboxylate with phenyl isocyanate reacted with different alkyl- and arylamines in the presence of sodium ethoxide to afford a series of chromeno[2,3-d]pyrimidin-4-one derivatives in good yields.
