Synthesis of Chiral Tropopodands Having L-Amino Acid Moieties and Ability of Their Metal Complexes as an Asymmetric Catalyst
摘要:
Optical active tropopodands (10 and 11) having neutral L-amino acids and L-histidine moieties were synthesized. Within their metal complexes, Pd complexes of histidine-tropopodands (11b and 11c) bearing bulky amide moieties showed good ability as an asymmetric catalyst in conjugate addition.
