The analysis of patterns of regioselectivity in cyclohexadienyl complexes illustrates the versatility and power of the iron-based methodology in reaction sequences that make multiple use of the metal to establish a series of chiral centres, The conversion of tricarbonyl(eta (4)-cyclohexadienone)iron(0) into the dimethyl malonate adduct 4, which contains two chiral centres at carbon besides the controlling chirality of the tricarbonyliron complex itself, provides an example of long-range asymmetric induction. The relative stereochemistry of the 1,3/1',2' product has been defined as S,S,R*,R*. Copyright (C) 2001 John Wiley & Sons, Ltd.
