(+/-)-Nocardione A (1), (S)-(-)-nocardione A, and (R)-(+)-nocardione B (2) were synthesized by starting from the enantiomers of propylene oxide and 5-benzyloxy (or methoxy)-1-tetralone. The absolute configurations of the naturally occurring (-)-1 and (-)-2 were established as (S).
(±)-Nocardione A (1), (S)-(-)-nocardione A 和 (R)-(+)-nocardione B (2) 通过以丙二醇环氧丙烷和 5-苄氧基(或甲氧基)-1-四氢萘酮的对映体为起始原料进行合成。天然存在的 (-)-1 和 (-)-2 的绝对构型均被确定为 (S)。
