Abstract: An Fe(NO3)3*9H2O-catalyzed cross-dehydrogenative coupling reaction between N-hydroxyphthalimide (NHPI) or N-hydroxysuccinimide (NHSI) and aldehydes or alcohols in the air has been described. This transformation provided an efficient approach to prepare N-hydroxyimide ester derivatives with wide substrate… read more here.

Abstract: ABSTRACT Regioselective protection of primary hydroxyl group in nucleoside and carbohydrate analogs was accomplished using dimethoxytrityl alcohol (DMTr-OH) or dimethylpixyl alcohol (DMPx-OH) in presence of copper(II)nitrate as a Lewis acid catalyst. Excellent selectivity was observed… read more here.
