Synthèse de bis - Δ1 - pyrazolines dérivées d'acétyléniques disubstitués dissymétriques
Written by sctunisie no commentsThe double cycloaddition 1,3 - dipolar of 2-diazopropane on dissymetrically activated substitued acetylenics has enabled us to synthesize some new organic products of the type bis - Δ1 -pyrazoline. However the transposed pyrazoline, derived directly from the benzoyl -7 carbomethoxy -8 bis - Δ1 -pyrazoline, was entirely identified and has proved the existence of the structure of this latter compound.
