A facile and efficient method for the synthesis of 3,4-disubstituted-1,2- dihydro-5H-pyrrol-2-ones 8a,c-f is reported. The method involves the hydrogenation of cyanohydrins of 2-alkyl-3-oxobutyric acid alkyl esters 1a-f, over Raney Ni at 50 psi to furnish hitherto unknown aminoacetyl intermediates 6a-f in quantitative yields which are cyclised to the targeted compounds.

Active methylene compounds undergo chemical condensation in water with aldehydes derived from yeast oxidation of the corresponding alcohols. Unsaturated compounds so obtained are then further reduced by yeast.
