title: Drugs derived from cannabinoids. 6. Synthesis of cyclic analogues of dimethylheptylpyran.
abstract: Two cyclic analogues 8 and 9 of dimethylheptylpyran (DMHP, 1) were synthesized by the Pechmann condensation of the resorcinol 4 with ethyl 4-methyl-2-cyclohexanone-1-carboxylate followed by Grignard addition with MeMgI. In selected pharmacological tests both analogues 8 and 9 were considered inactive compared to DMHP as CNS and cardiovascular agents.
