Abstract

During the lead-oriented synthesis of new heterocycles, ethyl 4-(cyanomethyl)-5-phenylisoxazole-3-carboxylate was identified as a key intermediate towards the synthesis of new isoxazolo[3,4-c]pyridine scaffolds. The key reaction was the catalytic hydrogenation of ethyl 4-(cyanomethyl)-5-phenylisoxazole-3-carboxylate using Raney/Ni followed by a selective ring closure reaction to afford 3-phenylisoxazolo[3,4-c]pyridin-7(6H)-one and its unsaturated analogue as new ring systems with lead-like properties.
