Crystal structure of 4-(4b,8a-dihydro-9H-pyrido[3,4-b]indol-1-yl)-7-methyl-2H-chromen-2-one
The title compound, C21H14N2O2, was prepared by Pictet–Spengler cyclization of tryptamine and 4-formyl coumarin. In the molecule, the dihedral angle between the mean planes of the coumarin and β-carboline ring systems is 63.8 (2)°. In the crystal, molecules are linked via N—H...N hydrogen bonds, for...
