A practical stereoselective synthesis of (6S)-5,6,dihydro-6-[(2R)-2-hydroxy-6-phenyl hexyl]-2H-pyran-2-one (1), a potent natural antifungal compound, is described. The sequence involves diastereoselective iodine-induced electrophilic cyclization, epoxide ring opening with a vinyl Grignard reagent and ring closing metathesis (RCM) as the key steps.
实用的立体选择性合成(6 S)-5,6,dihydro-6-[(2 R)-2-羟基-6-苯基己基] -2 H-吡喃-2-酮(1),一种有效的天然抗真菌剂化合物,描述。该序列涉及非对映选择性碘诱导的亲电环化,使用乙烯基格氏试剂的环氧化物开环和闭环复分解(RCM)作为关键步骤。
