A series of A-ring heterocyclic analogues of tetrahydrocannabinol were investigated. Chromanones 1a and 1b were functionalized by formylation with base and ethyl formate to give 6a and 6b. These formylketones were reacted with hydrazine, and Phenylhydrazine to give pyrazoles 7a,b,e, and f, respectively. When 6a and 6b were reacted wtih methylhydrazine, mixtures of methyl isomers 7c and 8a and 7d and
