Canonne, Persephone,Lemay, Gilles,Belanger, Denis

, p. 4167 - 4170 (2007/10/02)

Alkylated γ-spirolactones were prepared in one-step reactions in high yields from butane-1,4-diyl and pentane-1,5 diyldimagnesium dibromides and substituted cyclic anhydrides in tetrahydrofuran.In the light of experimental findings electronic and steric factors influence the regiospecificity of this reaction.
