important flaviviruses. It has a serine protease which is important for viral replication and this enzyme constitutes a suitable target for new anti-retroviral drugs. Herein we disclose a series of amide and esterpeptide mimetic inhibitors of serine proteases, all of them obtained via coupling reactions of isomannide derivatives with N-protectedaminoacids. The arginine derivative 19 showed 45% of inhibition

present the single‐step cyclization of (S)‐ or (R)‐α‐hydroxy‐β2‐ or α‐substituted‐α‐hydroxy‐β2, 2‐amino acids already incorporated within oligopeptides to 5‐aminomethyl‐oxazolidine‐2,4‐dione (Amo) rings. These scaffolds can be regarded as unprecedented β2‐ or β2, 2‐homo‐Freidinger lactam analogues, and can be equipped with a proteinogenic side chain at each residue. In a biomimetic environment, Amo rings
