摘要

Abstract: Carbamyl-l, 3, 2-dioxaphospholenes with pentavalent phosphorus were synthesized from a-ketoaldehydes, iswyanates, and trialkyl phosphites. The phospholenes were converted into phosphate esters of 0-keto-ahydroxyamides. These underwent very rapid hydrolyses to 0-keto-a-hydroxyamides. he 2, 2, 2-trialkoxy-1, 3, 2-dioxaphospholenes (1) are
