Pardon the Interruption: A Modification of Fischer's Venerable Reaction for the Synthesis of Heterocycles and Natural Products

Synlett. 2017;28(1):1-11. doi: 10.1055/s-0036-1588372.

Abstract

This account provides an overview of our laboratory's studies of an unusual variant of the Fischer indolization reaction. We describe the discovery of the so-called 'interrupted Fischer indolization' and the development of the reaction from a methodological standpoint. In addition, our efforts to evaluate and apply this methodology in the context of akuammiline alkaloid total synthesis are discussed.

Keywords: Fischer indolization; akuammilines; alkaloids; heterocycles; indoles; indolines; natural products; total synthesis.
