Disclosed herein is a method for converting cannabidiol (CBD) into a composition comprising Δ9-tetrahydrocannabinol ( Δ9-THC) and Δ8-tetrahydrocannabinol ( Δ8-THC) in which the composition has a Δ9-ΤΗΟ: Δ8-ΤΗΟ ratio of greater than 1.0:1.0. The method comprises contacting the CBD with a Lewis-acidic heterogeneous reagent under reaction conditions comprising: (i) an aprotic-solvent system; (ii) a reaction temperature that is less than a threshold reaction temperature for the Lewis-acidic heterogeneous reagent and the aprotic-solvent system; and (ill) a reaction time that is less than a threshold reaction time for the Lewis-acidic heterogeneous reagent, the aprotic-solvent system, and the reaction temperature. Methods for converting CBD into a composition comprising Δ9-THC and Δ8-THC in which the composition has a Δ9-THC: Δ8-THC ratio of greater than 1.0:1.0 under neat reaction conditions are also provided.
本公开了一种将
大麻二酚(CBD)转化为含Δ9-
四氢大麻酚(Δ9-THC)和Δ8-
四氢大麻酚(Δ8-THC)的组合物的方法,其中该组合物的Δ9-THC:Δ8-THC比率大于1.0:1.0。该方法包括将CBD与Lewis酸性异质试剂接触,在反应条件下进行反应,包括:(i)无极性溶剂系统;(ii)反应温度低于Lewis酸性异质试剂和无极性溶剂系统的阈值反应温度;以及(iii)反应时间短于Lewis酸性异质试剂、无极性溶剂系统和反应温度的阈值反应时间。还提供了在无净反应条件下将CBD转化为含Δ9-THC和Δ8-THC的组合物的方法,其中该组合物的Δ9-THC:Δ8-THC比率大于1.0:1.0。
