The title polycyclic alkaloid, C22H26N2O3, an indole derivative obtained from Melodinus yunnanensis, comprises three chiral C atoms and crystallizes as a racemate. Its seven-membered heterocyclic ring has a twisted conformation, with the N atom within the plane of the indole moiety and with two adjacent C atoms deviating in opposite directions from its plane by 0.756 (3) (methyl-ene C) and -0.802 (3) Å (methine C). In the crystal, pairs of N-H⋯O hydrogen bonds connect the mol-ecules into centros ...[more]
