Chiral aziridinyl radicals: an application to the synthesis of the core nucleus of FR-900482

摘要

An asymmetric route to the core nucleus of the antitumor agent FR-900482 utilizes the cyclization of an aziridinyl radical into a functionalized indole nucleus. The route employs a selective Polonovski reaction and the Hootele-Dmitrienko rearrangement to install two oxygen atoms.
