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.

A modified cyclopropanation of unsaturated ketones using dimethyloxosulfonium methide in ''super basic'' media generates exclusively the trans products in high yields (85-95%).
