Conversion of 1,3,5-triazinanes into 5-phosporyl-1,2,3,4-tetrahydropyrimidines is achieved efficiently through the microwave-assisted reaction with phosphoryl diazomethanes. Both trialkyl and triaryl 1,3,5-triazinanes were converted by diazomethyldiarylphosphine oxides, dialkyl diazomethylphosphonates, and alkyl diazomethyl(aryl)phosphinates and functionalized simultaneously in good to excellent yields. The reaction is a sequence of 1,3,5-triazinane fragmentation, tandem nucleophilic addition of the generated formaldimines and phosphoryl diazomethanes, and final N,N-acetalization.

1,3,5-三嗪与磷酰重氮甲烷的反应：获得 5-磷酰-1,2,3,4-四氢嘧啶


通过与磷酰重氮甲烷的微波辅助反应，可以有效地将 1,3,5-三嗪转化为 5-磷酰基-1,2,3,4-四氢嘧啶。三烷基和三芳基1,3,5-三嗪烷均可通过重氮甲基二芳基氧化膦、重氮甲基膦酸二烷基酯和重氮甲基（芳基）次膦酸烷基酯转化并同时官能化，收率良好至优异。该反应是一系列 1,3,5-三嗪烷断裂、生成的福尔马亚胺和磷酰重氮甲烷的串联亲核加成，以及最终的N , N-缩醛化。
