Dual mechanism of enamine-enamine rearrangement of 1,3-diaryl-3-(1-imidazolyl)propen-2-ones

, p. 593 - 594 (2002)
The formation of 1,3-diaryl-3-(1-imidazolyl)propen-1,3-diol that is an intermediate of enamine-enamine rearrangement of 1,3-diaryl-3-(1-imidazolyl)propen-1-ones constitutes the key stage of the dual mechanism of the rearrangement proper. The reaction of 1,3-diaryl-2,3-dibromopropan-1-ones with a primary amine provides 1,3-diaryl-3-iminopropan-1-ones as a result of enamine-imine prototropic rearrangement.

Results obtained and observations made by applying the title method for the synthesis of enaminones 5a-o, using triphenylphosphine as a thiophile and triethylamine as a base, are reported.The product distributions of the deprotonations of α-phenacylthio iminium bromides with and without thiophile and those known from thiouronium and heterocyclic thionium analogs are compared.Key words: Enaminones; α-phenacylthio iminium bromides; disulfides; thiiranes.
TRISUBSTITUTED THIAZOLES BY A 6?-ELECTROCYCLIZATION OF IMINOTHIOCARBONYL YLIDES
Corsaro, A.,Tarantello, M.,Purrello, G.
, p. 3305 - 3308 (2007/10/02)
Iminothiocarbonyl ylides are generated by a sulfur ligand exchange reaction of sulfonium salts and undergo a 6?-electrocyclic closure and aromatization to tri substituted thiazoles.Related carbonyl ylides preferred a 4?-electrocyclization.
