摘要:
The synthesis of a polar cannabinoid, 5',11-dihydroxy-Delta(8)-tetrahydrocannabinol (2), has been carried out. A key step in the synthesis is the reaction of an aryllithium derived from 1-(tert-butyldimethylsilyloxy)-5-(3, 5-dimethoxyphenyl)pentane with apoverbenone. Subsequent conversions provided diol 2, which has significantly less affinity for the cannabinoid receptor than Delta(8)-THC. (C) 1997 Elsevier Science Ltd.
