The optically active samin type of lignan, (1R,2S,5R, 6S)-6-(2-methoxy-4,5-methylenedioxyphenyl)-3,7-dioxabicyclo[3.3.0]octan-2-ol, was stereoselectively synthesized from L-glutamic acid via (2R,3R)-2-[(1S and R)1-[(tert - butyldimethylsilyl)oxyl-1-(2-methoxy-4,5methylenedioxyphenyl)methyl]-3-[(tert- butyldiphenylsilyl)oxylmethyl-1,4-butanediol.
木脂素的光学活性的samin类型为(1R,2S,5R,6S)-6-(2-甲氧基-4,5-亚甲基二氧苯基)-3,7-二氧杂双环[3.3.0] octan-2-ol。通过(2R,3R)-2-[(1S和R)1-[(叔丁基二甲基甲硅烷基)氧基-1-(2-甲氧基-4,5-亚甲基二氧基苯基)甲基] -3-[(叔) -丁基二苯基甲硅烷基)羟甲基-1,4-丁二醇。
