To probe the mechanism of dopamine receptors in drug addiction and look for potential new methods for treating this disease, we have designed and synthesized benzothiophene morpholine analogues that were considered as dopamine D3 receptor-selective ligands. Radioligand binding assay was used to determine the binding affinity of target compounds. Members of this class have great selectivity and binding affinity in D3 receptor. In addition, the ability of these compounds to mitigate the symptoms of addiction from opioids was investigated in animal behavior patterns, and we have found that two compounds (18a and 18d) have good affinity in the D3R and exhibit the efficacy of anti-drug addiction in morphine-dependent mice induced by naloxone.

A facile synthesis of multi-functionalized benzothiazonine was achieved by the rhodium-catalyzed denitrogenative annulation of 1-sulfonyl-1,2,3-triazole and thiochromone. In view of the excellent atom economy, broad substrate scope and easy availability of starting materials, the protocol provided an efficient strategy for the construction of mediumN,S-heterocycles.

A highly efficient asymmetric synthesis of chiral thiochromanones is developed via Cu(I)/phosphoramidite catalyzed asymmetric alkynylation of thiochromones under mild reaction conditions. The catalyst system is tolerant of various thiochromone precursors and terminal alkynes. The established asymmetric transformation provides different enatiomeric-enriched thiochromanones with more molecular complexity and enables access to chiral thioflavanones, a subgroup of flavonoid by further functionalization.
