| Outline of Final Research Achievements |
Optically-active double-stranded helices bearing chiral and achiral Co (II) salen complexes and achiral bipyridine N,N'-dioxide in the middle as metal- and organo-catalysts have been designed and synthesized. It was revealed that these one-handed double-helical catalysts remarkably enhanced and/or induced the enantioselectivity in the asymmetric reactions. Moreover, it was found that the [4+4] photocyclodimerization of a carboxylic acid monomer bearing a prochiral 2-substituted anthracene at one end took place regio- (head-to-tail (HT) or head-to-head (HH)), diastereo- (anti or syn), and enantioselectively in the presence of a series of optically-active amidine dimers with a variety of linkers used as templates through complementary amidinium-carboxylate salt bridges.
