摘要:
A four-step synthesis of the extracyclic, antimalarial indole natural product decursivine is described starting from commercial piperonyl bromide and serotonin (see scheme). A photoinitiated reaction cascade involving indole radical cation formation, rearrangement, radical recombination, rearomatization, elimination, and diastereoselective auto-acid-catalyzed closure of the dihydrofuran ring combine in a single step to conclude this remarkably efficient synthesis.
