摘要

(±)-Lysergic acid (1) has been synthesized via an economical 8-step route from 4- bromoindole and isocinchomeronic acid without the need to protect the indole during the synthesis. Initial efforts to form the simpler 3-acylindole derivatives first and then cyclize these were unsuccessful in the cyclization step.
