The urethanes and tosamides of 3-Hydroxypent-4-enylamine and its C1 C4 substituted derivatives undergo the palladium catalyzed intramolecular aminocarbonylation (0.1 equiv of PdCl2, 3.0 equiv of CuCl2, 3.0 equiv of NaOAc in acetic acid under ca. 1 atm of CO) to give selectively cis 3-hydroxypyrrolidine 2-acetic acidlactone and its C2 C5 substituted derivatives in good yields (66 – 90%), respectively
