Stereoselective total synthesis of (-)-galantinic acid
A concise, practical and stereoselective total synthesis of galantinic acid, constituent of the peptide antibiotic galantin, is reported. The title compound is obtained in six steps via Heathcock-Claisen condensation, Evans reduction and deprotection in 10% overall yield from protected serine. The route described herein thus constitutes the shortest and most efficient procedure for the preparation of the title compound disclosed so far.
