A facile reaction sequence, consisting of a palladium-catalyzed Sonogashira coupling, a cobalt-catalyzed Diels-Alder reaction and a subsequent cyclization initiated by a bromine-lithium exchange reaction, allows a three-componentsynthesis of tricyclic compounds. Thereby, structurally different functionalized compounds can be generated when functionalized dihalo-arenes, tosylated alkynols and substituted
We have developed a new type of n-pentenyl-type glycosides that can be activated by catalytic amounts of promoter, Hg(NTf2)2 or PPh3AuCl/AgNTf2, at room temperature. The mild activation conditions and outstanding stability of common protection/deprotection manipulations enable the enynyl donors to have broad applications in constructing various glycosidic bonds. Furthermore, under the Hg(NTf2)2-catalyzed

Provided are compounds having Formula (1), compositions thereof, and methods of modulating CFTR activity. Also provided are methods of treating a condition associated with decreased CFTR activity comprising administering to a subject an effective amount of a compound of Formula (1), optionally with other therapeutic agent(s).
The cationic gold(I)-catalyzed reaction of 1-alkynyl-2-allylsilylbenzenes with water results in intramolecular allylation of the alkynes via 7-exo-dig cyclization to give 1,4-dienes in good yield with excellent stereoselectivities.

trifluoromethylated DHP compounds. The reaction proceeded smoothly under mild electrolysis conditions. The broad substrate scope (>50 examples) and scalablesynthesis demonstrated the complexity-building potential of the strategy. Initial mechanistic studies reveal that cyclization may involve a radical process. This protocol may promote the further development of diversified synthesis of multi-substituted dihydropyran
