摘要：
Fourteen novel CB2 receptor selective cannabinoids were synthesized via initial Lewis acid catalyzed rearrangement of resorcinol precursors to obtain the cannabinoid moiety. These are the 1-methoxy-9-hydroxyhexahydrocannabinols and the 1-deoxy-9-hydroxyhexahydrocannabinols, with 1',1'-dimethylalkyl side chains of four to seven carbon atoms at C-3 of the cannabinoid nucleus. The cannabinols synthesized and described in this paper all exhibit greater affinity for the CB, receptor than for the CB1 receptor. Exceptionally high CB2 affinity was observed for 1-deoxy-9 beta-hydroxy-dimethylhexylhexahydrocannabinol (JWH-361, 9, n = 3) K-i = 2.7 nM and 1-deoxy-9 beta-hydroxydimethylpentyihexahydrocannabinol (JWH-300, 9, n = 2) K-i = 5.3 nM. In general, the stereochemistry of the 9-hydroxy group is important and the beta-orientation enhances both CB2 receptor affinity and selectivity. (c) 2005 Elsevier Ltd. All rights reserved.
