  摘要：

  本文介绍了一种简便的方法，即在大量过量的 2-甲基-2-丁烯存在下，用亚氯酸钠将δ9-四氢大麻酚醛 4 及其叔丁基二甲基硅烷衍生物方便地氧化成相应的酸，而不会发生δ9-双键的异构化。 在四氢呋喃中用四丁基氟化铵对 O 保护基进行脱保护处理，得到酸 2，总收率≥80%。对其他氧化剂和保护基团的研究表明，这是制备 9-羧基-δ9-四氢大麻酚的首选方法。

  Synthesis of racemic and optically active .DELTA.9-tetrahydrocannabinol (THC) metabolites

  摘要：

  The preparation of racemic and optically active DELTA-9-THC metabolites is described from synthon 13. Racemic synthon 13 is prepared in four steps (46%) from Danishefsky's diene. Optically active synthon 13 is prepared from perillaldehyde via the enone 22 in six steps (23% yield). Alternatively, nopinone can be converted to 13 in three steps (50% yield) via a cyclobutane ring cleavage. The acid-catalyzed condensation of 13 with olivetol (6a) and subsequent conversion to 11-hydroxy and 9-carboxyl DELTA-9-THC metabolites 2a and 4a is described, as well as the preparation of 1',1'-dimethylheptyl THC analogues 2b, 3b, and 4b from 5-(1',1'-dimethylheptyl)resorcinol (6c).

  A facile procedure is described whereby Δ9-THC aldehydes 4, as their tert-butyldimethylsilyl derivatives, are conveniently oxidized to the corresponding acids with sodium chlorite in the presence of a large excess of 2-methyl-2-butene without isomerization of the Δ9-double bond. Deprotection of the O-protecting group with tetrabutylammonium fluoride in tetrahydrofuran gave the acids 2 in an overall yield of ≥ 80%. A study of other oxidizing agents and protecting groups demonstrated that this is the procedure of choice for the preparation of 9-carboxy-Δ9-tetrahydrocannabinols.
