The first enantioselective total syntheses of indole alkaloids of the condylocarpine type are reported. (+)-Condylocarpine, (+)-isocondylocarpine, and (+)-tubotaiwine were prepared in high enantiomeric purity (er > 99:1) from (1S,5R)-hexahydro-1,5-methano-1H-azocino[4,3-b]indole-12-one 7b by way of five or six isolated intermediates.
首次报道了康定洛宾型吲哚生物碱的对映选择性全合成。(+)-康定洛宾、(+)-异康定洛宾和(+)-土藤太因可通过 5 或 6 个分离中间体,以(1S,5R)-六氢-1,5-亚甲基-1H-氮杂卓[4,3-b]吲哚-12-酮 7b 为原料,高对映体纯度(er > 99:1)制备得到。
