laboratories has provided evidence for the existence of a subsite within the CB1 and CB2cannabinoidreceptor binding domain corresponding to substituents at the benzylic side chain position of classical cannabinoids. The existence and stereochemical features of this subsite have now been probed through the synthesis of a novel series of (-)-Delta(8)-tetrahydrocannabinol analogues bearing C1'-ring substituents

cyanation is highly limited to very few types of organic compounds. Herein, we report the direct cyanation of cyclic thioacetals for accessing compounds with two different functional groups (thiocyano-thioesters) in one pot using sodium thiocyanate via photoredox catalysis. The protocol has been further extended for the direct cyanation of disulfides and diselenide to access aryl thiocyanates and aryl selenocyanate

Oxidative rearrangement of cyclicdithioacetals by the controlled C−S bond cleavage delivers the useful disulfide-linked-dithioesters via the visible light photoredox catalysis without using the external oxidizing reagent.

3-dithian-2-yl-phenyl]ethanone is obtained in excellent yield and purity. In addition, the generality of the technique is highlighted via the protection of numerous aldehydes and ketones affording the respective thioacetal/ketal in excellent yield (>99.1%) and purity (>99.9%), with space–time yields in the range of 0.44–1.10 g h−1.

Immunopharmacotherapy as an approach to combat drugs of abuse has become an active area of investigation. Marijuana is the most commonly used illicit drug in the U.S. The main active chemical in marijuana is Delta(9)-tetrahydrocannabinol (Delta(9)-THC); hence, monoclonal antibodies with high affinity and specificity for Delta(9)-tetrahydrocannabinol could be valuable immunopharmacotherapeutic intervention and diagnostic tools. We have synthesized immunoconjugates that induce an effective immune response to Delta(9)-THC and describe a convenient synthesis of radiolabeled Delta(9)-THC. We demonstrate the value and use of this probe to select anti-Delta(9)-THC antibodies that bind Delta(9)-THC with good affinity. The synthetic route to radiolabeled Delta(9)-THC has enabled the correct assessment of the affinity of these antibodies to their ligand and may facilitate future binding studies between Delta(9)-THC and its analogues and the cannabinoid receptors.
