Total synthesis of naturally occurring abietane diterpenoids via a late-stage Fe(iii)-bTAML catalysed Csp³–H functionalization

Abstract

A site-selective C–H functionalization strategy has been developed for a concise total synthesis of angustanol (5), majusanin B (2), majusanic acid D (1), angustanoic acid F (4), angustanoic acid E (6) and angustanoic acid G (3).
