Reductive decomplexation of π-allyltricarbonyliron lactone complexes: a new route to stereodefined acyclic 1,5-diols and 1,5,7-triols

Abstract

Treatment of π-allyltricarbonyliron lactone complexes with hydride donors causes decomplexation to acyclic alcohols. When sodium borohydride is used, decomplexation is accompanied by some degree of stereochemical scrambling and mixtures of saturated and unsaturated products are obtained. Treatment with sodium triacetoxyborohydride, however, affords only unsaturated products in which the alcohol stereocentres are preserved. Mechanisms for the decomplexation and isomerisation processes are proposed.
