Formation of cyclic ketene N-hydroxyaminals, 2-acylmethylene-1-hydroxy-imidazolidines, in the reaction of 1,2-bishydroxylamines with 1,3-ketoaldehydes

摘要

The reaction of aliphatic 1,2-bishydroxylamines with 1,3-ketoaldehydes generated in situ in acidic media leads to 2-acylmethylene-1-hydroxyimidazolidines, a new class of cyclic ketene N-hydroxyaminals. [References: 19]
