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( η 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 *.
