摘要

Cyanide anion was found to be a versatile catalyst in the aminolysis of nonactivated esters. A comparative study on various catalysts, including (dimethylamino) pyridine, 2- hydroxypyridine, imidazole, and sodium cyanide, in the ammonolysis of ethyl (S)-l-ethyl-2- pyrrolidinecarboxylate(1) in methanol showed sodium cyanide to be the superior catalyst. Furthermore, the reaction was completely stereoconservative; ie, less than 1% ...
