Optically active periplanone-B is manufactured through oxidizing (1RS, 4S, 5E)-isopropyl-7-methylene-5-cyclodecene-1-ol. The oxidized product is regioselectively enolized and then sulfenylated. The sulfenylated product is oxidized and then subjected to decomposition of the sulfoxide. The decomposed product is epoxidated, and the epoxidated product is converted into an enolate which is then oxidized. The oxidized product is oxidized and then regio- and stereoselectively epoxidated to obtain optically active periplanone-B.
旋光性的periplanone-B是通过氧化(1RS,4S,5E)-异丙基-7-甲基-5-环
癸烯-1-醇制造的。氧化产物被区域选择性地烯醇化,然后磺酰化。磺酰化产物被氧化,然后经过亚砜的分解。分解产物被环氧化,环氧化产物被转化为烯醇负离子,然后被氧化。氧化产物被再次氧化,然后被区域和立体选择性地环氧化,从而获得旋光性的periplanone-B。
