What is Stereoselectivity in the Reaction of Acyliron Complexes with Allylstannanes about?
The reaction of allylstannanes with a$-unsaturated acyliron complexes and AICl3 to give five-membered rings was found to be highly stereoselective. Reaction of the transcrotonyliron complex with allyltributyltin provided exclusively the adduct where the acyliron and methyl groups are trans. Reaction of the cis isomer provided the corresponding cis cyclopentane. Recently, we reported that a,P-unsaturated acyliron complexes react with allyltins and A03 to produce predominately cyclopentane derivatives' (Scheme 1). In some cases, predominately the open-chain product was obtained. These reactions were found to be highly stereoselective, producing only a single diastereomer in all cases. Since neither allyltins nor a&-unsaturated acylirons are conveniently available in stereochemical!y pure form2, the dependence of the reaction outcome on the stereochemical configuration of the starting alkenes was not determined in the preliminary communication. Herein we report how the double bond configuration of the starting a&unsaturated acyliron complex affects the outcome of the reaction.
