practical asymmetricsynthesis of 3,4-disubstitutedprolinederivatives has been realized with high stereoselectivity and moderate yield. The key steps involved are desymmetric ring-opening reaction of commercially available anhydrides, intramolecular Strecker reaction and thermodynamically controlled cyanide hydrolysis. Based on this methodology, the synthesis of HCV proteaseinhibitorTelaprevir was achieved
