-037Synthesis and Reduction Ability of Borane Complexes of 2-Aminopyridine Derivative Having a Chiral Center at the Amino Nitrogen.-New chiral amine boranes are synthesized and studied for their reducing ability toward carbonyl compounds. While reduction of cyclohexanone derivative (I) proceeds with good to high diastereoselectivity, no significant stereoselection is observed in the reduction of acetophenone. -(YAMAGUCHI, Y.; TAKADA, A.; OKAMOTO, Y.; J.
