Abstract

Diastereoselectivity of allylations of enantiopure 3- and 4-substituted eta(4)-(1Z)-(sulfinyldienal)iron(0) tricarbonyl complexes is dependent on the nature of the alkyl substituent. For 1-sulfinyl-1,3-pentadien-5-al iron complexes (11a-d), the aldehyde predominately reacts through the s-cis conformer, with diastereoselectivites as high as 95:5 (for homoallylic alcohol 13d). For 3-formyl-1-sulfinyl-1,3-butadiene iron complexes (12a,b), the aldehyde predominately reacts through the s-trans conformer (diastereomer ratio for homoallylic alcohol, 14b, 89:11).
