Highly diastereoselective Michael addition of lithium diorganocuprates to the half-ester of 1,1'-binaphthalene-8,8'-diol gave β-substituted esters with high enantiomeric excess after methanolysis. The optically active phenolic sesquiterpenes turmeronol A (1) and B (2) have been synthesized using this reaction as a key step.
