Abstract
1,3-bis(3-phenyl-3-oxopropanoyl)benzene (BPOB) was prepared by Claisen condensation of aceto-phenone and dimethyl isophthalate and characterized by elemental analysis, MS, 1H NMR, UV absorption spectrum, solid-state circular dichroism (CD) spectra, and X-ray single-crystal diffraction. The X-ray crystallographic data indicated that BPOB crystallized in a Sohncke group P212121, UV and 1H NMR showed that the enol tautomer was the most dominant form in solution, and the solid-state CD spectra and repeated recrytallization revealed that the formation of chiral BPOB crystals could be regarded as crystallization-induced asymmetric synthesis.
