Structure of 3-methyl-2,3,4,4a,5, 10b-hexahydro-1H-spiro[chromeno[3,4-c] pyridin-1,1'-cyclohexane]-2,4,5-trione

Abstract

3-Methyl-2,3,4,4a,5,10b-hexahydro-1H-spiro[chromeno[3,4-c]pyridin-1,1'-cyclohexane]-2,4,5-trione is obtained by the interaction of methyl 1-bromocyclohexane carboxylate with zinc and N-methyl-2-oxo-2H- chromen-3-carboxamide, and its structure is determined by the single crystal X-ray diffraction method.
