A simple route for the enantioselective synthesis of key intermediates (11 and 12) for the total synthesis of forskolin has been developed starting from acid 6 and (S)-alcohol 5. The latter is prepared by enantioselective catalytic CBS reduction of dienone 3, and is converted by an intramolecular Diels-Alder reaction to tricyclic lactone 9.
从酸6和(S)-醇5开始,已开发出一种用于对福斯高林进行全合成的关键中间体(11和12)的对映选择性合成的简单路线。后者通过对映二烯酮3的对映选择性催化CBS还原制备,并通过分子内Diels-Alder反应转化为三环内酯9。
