摘要

3, 3, 5-Trimethyl-2-cyclohexylidene iminium salts were reduced with 1, 4- dihydronicotinamide sugar pyranosides to give optically active 3, 3, 5- trimethylcyclohexanone in enantiomeric excess ranging over 3-31%. The product stereochemistry changed sensitively with structural variation (including anomers, epimers, and deacetylation) of sugar residues. The reduction by more simplified chiral models, N 1- ...
