Abstract

A highly efficient and environmentally friendly method for the synthesis of 3-alkoxy-1,1,1-trifluoropropan-2-ols is presented. The approach involves ring-opening reaction of 1,1,1-trifluoro-2,3-epoxypropane with structurally different long-chain alcohols under microwave irradiation at room temperature in the absence of solvent. These chemicals are precursors of the corresponding trifluoromethyl ketones, potent inhibitors of human and murine liver microsomes and porcine liver esterase.

Key words

1,1,1-trifluoro-2,3-epoxypropane - ring opening - trifluoromethyl carbinols - trifluoromethyl ketones - microwave catalysis
