Mercuric acetate in organic synthesis: A simple procedure for the synthesis of pyrazolines
Rai, K.M. Lokanatha,Linganna
, p. 3737 - 3744 (2007/10/03)
Reaction of aldehyde hydrazones (1) with mercuric acetate leads to the formation of nitrile imines (2) which can react in situ with olefins to produce 1,3,5-trisubstituted 2-pyrazolines (4) in good yield.
CHLORAMINE-T IN HETEROCYCLIC SYNTHESIS; A SIMPLE PROCEDURE FOR THE GENERATION OF NITRILIMINES AND ITS APPLICATION TO THE SYNTHESIS OF PYRAZOLINES
Rai, Lokanatha,Hassner, Alfred
, p. 2799 - 2808 (2007/10/02)
A new method of generating nitrilimines is described.It involves the reaction of aromatic as well as aliphatic aldehyde hydrazones with chloramine-T.In the presence of olefins pyrazolines are obtained in good yield.
Dihalogentriphenylphosphoranes in Heterocyclic Synthesis; 15. A Simple One-Pot-Procedure for the Generation of Nitrilimines with the Aid of Dihalogentriphenylphosphoranes: 1,3-Dipolar Cycloadditions and 1,5-Electrocyclizations
Wamhoff, Heinrich,Zahran, Magdy
, p. 876 - 879 (2007/10/02)
A simple and versatile one-pot procedure for the in situ generation of nitrilimines from N-acyl hydrazines is described. 1,3-Dipolar cycloadditions and 1,5-electrocyclic ring closures are carried out.Unsymmetrically substituted dipolarophiles show typical
1,3-Dipolar Cycloadditions, 89. New Contributions to the Chemistry of Diphenylnitrilimine
Clovis, James S.,Fliege, Werner,Huisgen, Rolf
, p. 3062 - 3070 (2007/10/02)
Methyl propiolate, tetrolate, and phenylpropiolate combine with diphenylnitrilimine (1) to afford regioisomeric cycloadducts; the preferential orientation shifts in the sequence given from the pyrazole-5-carboxylic ester to the 4-carboxylic ester.Correspo
