Abstract

Abstract Malonic acid esters of trans-1-substituted-3-trifluoromethyl-2-butene-1-ols underwent stereoselective, SET induced cyclization reaction sequence in the presence of iodine, potassium carbonate and quaternary ammonium salt. The allyl substituents of the starting materials influenced the diastereoisomeric composition of the new products.
