Synthesis and Characterization of Chiral Nitrobenzaldehyde - Schiff Base Ligands
Molecules, 2003 Three chiral nitrobenzaldehyde/Schiff base ligands (2a-c) were prepared by the reaction of ortho, meta, and para-NO2 substituted benzaldehydes (1a-c) with (1R,2R)-(-)-1,2-diaminocyclohexane. The structures of ligands 2a-c were characterized by IR, 1H-NMR,

KINETIC STUDIES ON THE ALKYLATING ACTIVITY OF CERTAIN NEW CHALCONES OF ACETYLPYRIDINES [PDF]
Bulletin of Pharmaceutical Sciences. Assiut University, 1995 The synthesis of a number of chalcones derived from acetylpyridines and some p-substituted benzaldehydes has been accomplished. These compounds were evaluated for their alkylating activity by kinetic studies of their reaction with 2-mercaptoethanol ...
