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.
二愈创木酸锂与 1,1'-联萘-8,8'-二醇的半酯进行高非对映选择性迈克尔加成反应,甲醇分解后得到对映体过量的 β-取代酯。以该反应为关键步骤,合成了具有光学活性的酚类倍半萜化合物松柏醇 A (1) 和 B(2)。
