Dg. Mazhukin et al., Formation of cyclic ketene N-hydroxyaminals, 2-acylmethylene-1-hydroxy-imidazolidines, in the reaction of 1,2-bishydroxylamines with 1,3-ketoaldehydes, MENDELEEV C, (2), 2000, pp. 69-NIL_6
The reaction of aliphatic 1,2-bishydroxylamines with 1,3-ketoaldehydes gene
rated in situ in acidic media leads to 2-acylmethylene-1-hydroxyimidazolidi
nes, a new class of cyclic ketene N-hydroxyaminals.
