The conversion of the amino group of chiral amines, amino alcohols, amino acids and their esters into chiral 2-substituted pyrrole derivatives with various halogeno enones is described. The conversion works in good yield and without racemization. The synthesis of 2-phenylpyrrole derivatives was possible with amino alcohols but not with amino acids or their esters.

Efficient synthesis of 1,2-disubstituted homochiral pyrroles has been achieved by a two-component coupling of chloroenones and amine compounds on the surface of silica gel without any solvent under microwave irradiation.
