Abstract

(+)-Alstonlarsine A is a recently isolated monoterpenoid indole alkaloid, possessing a novel pentacyclic skeleton and interesting biological activity, making it an attractive target for synthetic chemists. In this article we focus on its total synthesis, grounded on enamine formation/Diels–Alder reaction domino sequence, as well as a novel methodology for indole C2 functionalization via carbenoid insertion, which could also allow for the synthesis of other indole alkaloids possessing cycloalka[b]indole subunits.
