S. Ianelli et al., CONFORMATION AT THE AMIDE-N ATOM OF 1-CARBOXAMIDE INDOLE-DERIVATIVES, Acta crystallographica. Section C, Crystal structure communications, 51, 1995, pp. 1341-1345
Knowledge of the conformation at the amide N atom of N-3-methoxyphenyl
-2-(5-methoxyindole)carboxamide, C17H16N2O3, and N-methyl-N-phenyl-2-(
5-methoxyindole)carboxamide, C17H16N2O2, allows an interpretation of t
he H-1 NMR behaviour of the two compounds. The structures and conforma
tions of the two molecules are compared.
