A new synthetic route for the γ-lactone precursors of hydroxyethylene dipeptide isosteres

δ-Phthalimido-γ-ketoesters were obtained by the Pd catalyzed coupling reaction between acid chlorides and organozinc reagents derived from β-iodoesters, and were converted into the γ-lactones precursors of Phe-ψ[H.E.]-Ala and Phe-ψ[H.E.]-Pro (15a,b-18a,b).

Studies of HIV-1 protease inhibitors. II. Incorporation of four types of hydroxyethylene dipeptide isosteres at the scissile site of substrate sequences

Human immunodeficiency virus type 1 (HIV-1) protease inhibitors containing four types of hydroxyethylene dipeptide isosteres were designed and synthesized. These inhibitors consist of eight stereoisomers of phenylalanylproline (Phe-Ψ[H.E.]-Pro), four ster
