A synthesis of the banana weevil pheromone component (1 S,3 R,5 R,7 S)-sordidinstarting from ( S)-2-(2-ethyl-1,3-dioxolanyl)propan-1-oland ( R)-4-hydroxypentan-2-one is described.No epimerization was observed for the final, intramolecular, acid-catalyzedcyclization step using aqueous oxalic acid.
从 (S)-2-(2-ethyl-1,3-dioxolanyl)propan-1-oland (R)-开始合成香蕉象鼻虫信息素成分 (1 S,3 R,5 R,7 S)-sordidin描述了 4-羟基戊烷-2-one。对于使用草酸水溶液的最终的、分子内的、酸催化的环化步骤没有观察到差向异构化。
