Crystal structure and Hirshfeld surface analysis of 2-(di-meth-oxy-meth-yl)phenyl (3a RS ,6 SR ,7 RS ,7a SR )-1-oxo-2-phenyl-1,2,3,6,7,7a-hexa-hydro-3a,6-ep-oxy-iso-indole-7-carboxyl-ate.

Abstract

The mol-ecular structure of the title compound, C24H23NO6, exhibits stability due to four intra-molecular C-H⋯O inter-actions that form rings with S(6), S(9), S(5), and S(5) motifs. In the 7-oxabi-cyclo-[2.2.1]hept-2-ene unit, the five-membered rings and the pyrrolidine ring all adopt envelope conformations. In the crystal, the mol-ecules are connected by C-H⋯O inter-actions, creating a three-dimensional framework. The mol-ecules are further connected by C-H⋯π inter-actions, forming layers parallel to the (101) plane. Important inter-molecular inter-actions highlighted by Hirshfeld surface analysis are H⋯H (54.6%), C⋯H/H⋯C (21.6%) and O⋯H/H⋯O (21.3%) contacts.
