The Hofmann-like fragmentation induced by n-acylation of 1-methyl-1-AZA-4-cyclanones and its use in the synthesis of 2-AZA-hydrindanones and 2-AZA-decalones
Summary: The N-methyl-piperidone 4a was fragmented to the vinylketonic acrylamide 9a by successive treatment with acryloyl chGride and Hiinig's base. The Z-azahydrindandione pa resulted from the cyclization of 9a in the form of its enol dimethylterbutyl ether. N-me- ...
