摘要：

Expeditious enantioselective syntheses of (+)~quebrachamine (6), (-)-aspidospermidine (7), (+)-demethoxy-aspidospermine (8), and (-)-eburnamonine (9) were accomplished starting from (S)-lactone 1. The syntheses also complete formal, total syntheses of 12 other indole alkaloids of the Aspidosperma and Hunteria types. The key step in the synthesis of (+)-quebrachamine (6) was the Pictet-Spengler condensation of chiral C9 unit 10, derived from 1, with tryptamine. Another C9 unit (15) was also prepared from 1 and utilized for the syntheses of three other alkaloids, 7, 8, and 9. © 1990, American Chemical Society. All rights reserved.
