Abstract: The preparative resolution by preferential crystallization (PC) of proxyphylline has been achieved despite the existence of a stable racemic compound. This is enabled through the careful selection of a solvent in which both the racemic… read more here.

Abstract: A racemic compound, (S*)-3-[(1R*,3R*)-3-hydroxy-1,3-dihydroisobenzofuran-1-yl]-2-(naphthalen-1-yl)isoindolin-1-one (3), was synthesized and found to exhibit four distinct sets of 1H and 13C NMR signals in CDCl3 solution. The four sets of 1H NMR signals displayed relative integration ratios of… read more here.
