Synthesis of chiral sulfonamide/Schiff base ligands
摘要:
We report a facile two step synthesis of chiral ligands for bonding to transition-metals. The ligands are easily prepared from trans-1,2-diaminocycrohexane by reaction with sulfonyl chlorides to give amino-sulfonamide compounds. These intermediates are then condensed with salicylaldehyde derivatives to provide sulfonamide/Schiff base compounds which represent a new class of chiral ligands. (C) 1998 Elsevier Science Ltd.
