摘要

Peronatins A and B and 7, 7'-dimethoxyperonatin B, originally isolated from the damaged fruiting bodies of Collybia peronata and Tricholoma scalpturatum, have been synthesized by oxidative dimerization of 2-alkylindoles. The conversion of peronatin A to peronatin B was shown to be catalyzed by Brønsted acids in chloroform solution and inhibited by triethylamine, implicating a retro-Mannich/Mannich isomerization pathway under these ...
