Abstract: The α-alkylation products of γ-butyrolactone can be gained via two simple and convenient steps:(E)-α-Alkenyl-γ-butyrolactone compounds were synthesized from condensation of corresponding aromatic aldehydes and γ-butyrolactone, using common base such as MeONa and EtONa. Then the (E)-α-Alkenyl-γ-butyrolactones were reduced to α-alkyl-γ-butyrolactones by using sodium hypophosphite with Pd/C catalyst, which is named to be reaction of catalytic transfer hydrogenation.

Key words: α-alkylation of γ-butyrolactone, condensation, Pd/C-sodium hypophosphite, catalytic transfer
