A second-generationstrategy for construction of (+)-nodulisporic acids A and B based on the development of a new, effective modular indolesynthesis exploiting a sequential Stille cross-coupling/Buchwald−Hartwig union/cyclization tactic is disclosed. This strategy evolved due to the considerable acid instability of the C(24) hydroxyl group observed in several advanced intermediates during our first-generation
