A versatile approach to cis-5-substituted 4-hydroxy-2-pyrrolidinones: asymmetric synthesis of angiogenesis inhibitor streptopyrrolidine

, 2009
A concise, flexible, and highly diastereoselective approach to cis-5-alkyl-4-hydroxy-2-pyrrolidinones 1 is described. The key step is an ammonium acetate-assisted catalytic hydrogenation of the enamides 9, derived in two steps from malimides 6a,b as we ...
