Total Synthesis of the Marine Phosphomacrolide, (−)-Enigmazole A, Exploiting Multicomponent Type I Anion Relay Chemistry (ARC) in Conjunction with a Late-Stage Petasis–Ferrier Union/Rearrangement

Abstract

An effective late-stage large-fragment union/rearrangement exploiting the Petasis-Ferrier protocol, in conjunction with multicomponent Type I Anion Relay Chemistry (ARC) to access advanced intermediates, permits completion of a convergent, stereocontrolled total synthesis of the architecturally complex phosphomacrolide (-)-enigmazole A (1).
