continuation of studies on the synthesis of side-chain analogues of Δ6a,10a-tetrahydrocannabinol as potential therapeutic agents has led to the syntheses of a possible metabolite 1-hydroxy-6,6,9-trimethyl-7,8,9,10-tetrahydro-6H-dibenzo[b,d]pyran-3-ylacetic acid (1) and 2-(1-hydroxy-6,6,9-trimethyl-7,8,9,10-tetrahydro-6H-dibenzo[b,d]pyran-3-yl)pent-4-ynioc acid (17c). The Pechmann condensation of ethyl 4-met
继续研究作为潜在治疗剂的Δ6a ,10a-四氢大麻酚侧链类似物的合成已经合成了可能的代谢产物1-羟基-6,6,9-三甲基-7,8,9, 10-四氢-6 H-二苯并[ b,d ]吡喃-3-基乙酸(1)和2-(1-羟基-6,6,9-三甲基-7,8,9,10-四氢-6 H -二苯并[ b,d] pyran-3-yl)pent-4-yinooc acid(17c)。4-甲基-2-氧代环己烷-1-甲酸乙酯与3,5-二羟基苯基乙酸甲酯的Pechmann缩合反应(11),然后通过Grignard反应,生成吡喃(1)。炔丙基乙酸(17c)合成的关键步骤是在相转移催化下丙二酸酯(15)的炔丙基化。
