Heterocyclic Derivatives of Curcumin: Crystal Structure of 3,5-Bis[β-(4-acetoxy-3-methoxyphenyl)ethyl]isoxazol

Abstract

C₂₅H₂₇NO₇ is monoclinic, P2₁/n. The unit-cell dimensions at 293 K are a = 14.031(1), b = 10.717(1), c = 32.093(3)Å, β = 94.633(2)°, V = 4810.1(7)ų, D_x = 1.252 g/cm³, and Z = 8. The R value is R = 0.065 for 8486 reflections. The isoxazol rings adopt a half-chair conformation. The molecule is stabilized by several C-H…O intermolecular contacts.
