Abstract

An 11-step approach to tricyclic compound 42, which contains the alkaloidal nucleus of the marine natural product sarain A (1), has been developed. Pivotal steps in the construction of 42 include stereospecific intramolecular dipolar [3 + 2]-cycloaddition of an azomethine ylide generated from aziridine 27 to afford bicyclic lactam 28 and a novel intramolecular allylsilane/N-tosyliminium ion cyclication of 41 to produce the tricycle.
