Methyl 9-p-tolyl-8a,9,9a,10,11,12,13,14a-octahydro-8H-benzo[f]chromeno[3,4-b]indolizine-8a-carboxylate

Abstract

In the title compound, C28H29NO3, the fused pyrrolidine and piperidine rings of the octa­hydro­indolizine unit exhibit envelope and chair conformations, respectively. The dihedral angle between the naphthalene ring system and the benzene ring is 40.37 (5)°. The crystal packing is stabilized by weak inter­molecular C—H⋯O inter­actions.

“…1), the cyclohexenone ring (C1-C6) is puckered [maximum puckering amplitude Q = 0.554 (4) (3) A ˚and exhibits an envelope conformation on atom C2 (Cremer & Pople, 1975). The bond lengths and bond angles agree with those of previously reported related compounds (Gunasekaran et al, 2009;Mertsalov et al, 2021;Chandana et al, 2021;Ganesha, Nizamuddin et al, 2023;Ganesha et al, 2022;Sreenatha et al, 2018Sreenatha et al, , 2020Sreenatha et al, , 2022Lakshminarayana et al, 2009Lakshminarayana et al, , 2010Lakshminarayana et al, , 2022Madan Kumar et al, 2018;HariPrasada et al, 2023). The dihedral angle between the mean plane of the cyclohexenone (C1-C6) and fluorobenzene rings (C7-C12 and C17-C22) are 62.3 (2) and 84.9 ( 2…”
