A challenging step in the preparation of tetrahydrocannabinol analogs is an acid-catalyzed intramolecular cyclization of the cannabidiol precursor. This step typically affords a mixture of products, which requires extensive purification to obtain any pure products. We report the development of two continuous-flow protocols for the preparation of (-)--Δ-tetrahydrocannabinol and (-)--Δ-tetrahydrocannabinol.
在四氢大麻酚类似物的制备中，具有挑战性的一步是大麻二酚前体的酸催化分子内环化。这一步通常会得到产物的混合物，需要进行大量的纯化才能得到任何纯的产物。我们报告了两种(-)--Δ-四氢大麻酚和(-)--Δ-四氢大麻酚制备的连续流方案的开发。
