Carbonylation (hydroformylation and hydrocarbalkoxylation) and enantioselective carbonylation of some methacrylic acid derivatives

The hydroformylation of methyl methacrylate (1) or t-butyl methacrylate (2) takes place with fair to good chemoselectivity, the regioselectivity depending on the catalyst precursor used.By contrast, methacrylonitrile (3), methacrylamide (4), and N-benzyl-methacrylamide (5) undergo hydroformylation followed by subsequent reactions.The formyl product formed is reduced to the corresponding 2-cyano-2-methylpropan-1-ol in the case of 3, and undergoes cyclization to 2-methyl-2,3-dehydrobutyrolactames for 4 and 5.Under conditions of hydrocarbalkoxylation in the presence of palladium catalysts, 4 gives 3-methylsuccinimide.In the enantioselective reactions, extents of asymmetric induction of about 20-50percent have been obtained.
