In this study, a reaction pathway for converting the psychoactive compound Δ9-THC into the nonpsychoactive cannabidiol (CBD) was proposed. Related cannabinoids, including Δ8-THC and cannabinol (CBN), were also examined. The transformation proceeds via two key steps: (i) hydrogen elimination and cyclic ether ring cleavage, and (ii) hydrolysis to form hydroxyl groups, facilitated by boron...
Lysergic acid diethylamide (LSD), a semisynthetic ergoline alkaloid analogue and hallucinogen, is a potent psychoplastogen with promising therapeutic potential. While a variety of synthetic strategies for accessing ergoline alkaloids have emerged, the complexity of the tetracyclic ring system results in distinct challenges in preparing analogues with novel substitution patterns. Methods of...
The key tricyclic intermediate 3a, for the total synthesis of the C(20)-nor analogue of salvinorin A, was prepared in seven steps from 3-furaldehyde. Key steps involved a highly regio- and diastereoselective Lewis acid assisted Diels-Alder reaction followed by base-promoted epimerization and a completely stereoselective conjugate reduction.
A norbornene-mediated palladium-catalyzed sequence is described in which two alkyl-aryl bonds and one alkenyl-aryl bond are formed in one pot with use of microwave irradiation. A variety of symmetrical and unsymmetrical oxygen-, nitrogen-, silicon-, and sulfur-containing tricyclic heterocycles were synthesized from a Heck acceptor and an aryl iodide containing two tethered alkyl halides. This...
[reaction: see text] Treatment of salvinorin A (1a) with KOH in MeOH gave the enedione 3, for which the dienone structure 7 was recently proposed. Also isolated, after methylation, were the secotriesters 4a-c. A mechanism for this unusual series of autoxidations is proposed. Surprisingly, 4a showed weak affinity at the kappa-opioid receptor. Divinatorins A-C (2a-c) showed no affinity at opioid...
