A Facile Synthesis of 3,4-Disubstituted-1,2-dihydro-5H-pyrrol-2-ones. — A facile
efficient method for the synthesis of title compounds (IV) is reported. The method
11- 128 and
involves the hydrogenation of cyanohydrins (I) to the hitherto unknown aminoacetyl
intermediates (III). The results suggest that the reduction of the nitrile group in the
cyanohydrins in the presence of an ester group requires specific conditions so as to keep
the hydroxyl as well as the ester groups intact. — (BHANDARI*, K.; SHARMA, V.
