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.
本论文报告了一种简洁、实用和立体选择性的伽兰亭酸全合成方法,伽兰亭酸是多肽抗生素伽兰亭的成分。标题化合物通过 Heathcock-Claisen 缩合、Evans 还原和脱保护等六个步骤从受保护的丝氨酸中获得,总收率为 10%。因此,本文所描述的路线是迄今为止公开的制备标题化合物的最简短、最有效的程序。
