Magedov,Smushkevich
, p. 845 - 848 (2007/10/02)
A new preparative method is reported for the synthesis of 4,5-disubstituted 1,2-dimethyl-1H-pyrazol-3(2H)-ones 5a-e,g-k from N,N-diacyl-N,N'-dimethylhydrazines 1a-e,g,h,j,k. The method is based on the intramolecular formation of thc 4,5-bond in the pyrazo
Anionic 3,4-diaza[3,3]sigmatropic rearrangements of N,N′-diacylhydrazines
Endo, Yasuyuki,Shudo, Koichi
, p. 4517 - 4520 (2007/10/02)
N,N′-Diacylhydrazines rearrange under basic conditions to afford 1,2-disubstituted succinamides. The rearrangement can be rationalized in terms of [3,3]sigmatropic shifts of biscarboxamide enolates.
New Diastereoselective Method for Constructing a Carbon Chain by Conversion of N,N'-Dialkyl-N,N'-diacylhydrazines to threo-1,2-Dicarboxylic Acid Derivatives
Magedov, Igor V.,Smushkevich, Yuri I.
, p. 1686 - 1687 (2007/10/02)
A diastereoselective method is described for constructing a carbon chain by conversion of N,N'-dialkyl-N,N'-diacylhydrazines (1a-f) to dialkyldiamides of threo-1,2-dicarboxylic acids (3a-f).
