Heterocyclic compounds shown in Formula (I) suitable for inhibiting or regulating the activity of Janus kinase (JAK), particularly tyrosine kinase 2 (TYK2). The compounds are useful for preventing and/or treating relevant JAK-mediated diseases, such as autoimmune diseases, inflammatory diseases, and cancers.
Palladium(0)-catalyzed allylation of highly acidic and non-nucleophilic arenesulfonamides, sulfamide, and cyanamide. II. Formation of medium and large heterocycles
Arenesulfonamides 10, cyanamide 29, and sulfamide 32 react with allylic bis-carbonates 8 (Z and E) and 9 under Pd(0)-catalysis to afford medium and large unsaturated heterocycles instead of three and/or five-membered ring compounds. Stable 15-membered palladium-containing rings were also isolated from arenesulfonamides and 8, with three trans olefinic systems coordinated to the metal. NMR and MALDI-TOF

1,5-diazacyclooctane-3,7-derivatives as precursors of the 3,7-diaza[3.3.0]bicyclooctane and 3,7,10-heterocyclic[3.3.3]propellane ring systems

A simple synthesis of 3,7-disubstituted-1,5-diazacyclooctanes from p-toluenesulfonamides and 3-chloro-2-chloromethylpropene has been developed. Unusual transannular reactions in these eightmembered ring intermediates provide easy access to novel 3,7-diaza[3.3.0]bicyclooctane and 3,7,10-heterocyclic[3.3.3]propellane ring systems.
