Hydroxy- and alkoxycarbonylation reactions constitute important industrial processes in homogeneous catalysis. Nowadays, palladium complexes constitute state-of-the-art catalysts for these transformations. Herein, we report the first efficient platinum-catalysed alkoxycarbonylations of olefins including sterically hindered and functionalized ones. This atom-efficient catalytic transformation provides

N-benzoyl-2-hydroxy-4-methylpyrrolidine, the key intermediate for the doublecarbonylation and the reductive annulation, is obtained selectivity in a Rh4(CO)12-catalyzed reaction of N-methallylamide. The hydrocarbonylations of this cyclic hemiamidal catalyzed by RhCl(PPh3)3, Co2Rh2(CO)12, and Co2(CO)8 give the corresponding doublecarbonylation product (2-formylpyrrolidine), reductive annulation product (pyrrolidine)
