Abstract

Δ2-Oxazolinium and thiazolinium cations with or without an appendage at any of the heteroatoms transfer their C (2) units at the carboxylic acid oxidation level to binucleophiles and provide the corresponding heterocycles, thus mimicking carbon transfer reactions exhibited by THF models, N-methyl N'-tosyl/acetyl imidazolinium cations. However, these azolinium cations react with phen ethyl amine and tryptamine to furnish their N-acyl ...
