Abstract

The compound O-acryloylated 2,3-dihydrobenzo[b]furan-5-ol (2) described in the title (chemical formula C19H18O4) was synthesized through the acryloylation reaction in anhydrous dichloromethane from the corresponding trans-2-(4-methoxyphenyl)-3-methyl-2,3-dihydrobenzo[b]furan-5-ol derivative (1), an adduct easily obtained using the Lewis acid-promoted formal [3 + 2] cycloaddition reaction. Molecular characterization was performed by Fourier Transform-Infrared (FT-IR), Gas Chromatography-Mass Spectrometry (GC-MS), 1H and 13C NMR and crystallographic characterization was carried out by X-ray diffraction (XRD) of polycrystalline samples. The title compound crystallized in a monoclinic system and unit-cell parameters are reported [a = 8.067(2) Å, b = 8.803(2) Å, c = 22.405(5) Å, β = 91.62(3)°, unit-cell volume V = 1590.7(6) Å3 and Z = 4]. All measured lines were indexed with the P21/c (No. 14) space group.
