Michael addition of formaldehyde dimethylhydrazone to nitroolefins. A new formyl anion equivalent
Lassaletta, Jose-Maria,Fernandez, Rosario
, p. 3691 - 3694 (2007/10/02)
Formaldehyde dimethylhydrazone readily adds to simple nitro-olefins in the absence of base giving β-nitrodimethylhydrazones in very high yields. The corresponding β-nitroaldehydes can be obtained by ozonolysis.
