ACYLHYDRAZONES OF 3H-INDOL-3-ONE
Berdinskii, I. S.,Maslivets, A. N.,Orlova, L. D.
, p. 814 - 816 (2007/10/02)
The reaction of 3-ethoxalyl- and acetylhydrazones of isatin with arylmagnesium bromide leads to the glycoloyl- and acetylhydrazones of 2-aryl-3H-indol-3-one as a result of the participation of the α-carbonyl group of the isatin ring in the reaction.
