Sulfamidation of benzylic alcohols was achieved for the first time using nucleophilicsubstitutions catalyzed by FeCl3, as a Lewis acid. A variety of N‐benzyl‐substituted sulfamides were produced efficiently by this novel protocol.
The present invention provides a compound having antiviral effects, particularly having growth inhibitory activity on influenza viruses, a preferred example of the compound being a substituted 3-hydroxy-4-pyridone derivative prodrug having cap-dependent endonuclease inhibitory activity.
The present invention relates to compound of formula (I) wherein R1, R2, R3, R4, R5, R6, R7, and X are as defined in the description and claims, and pharmaceutically acceptable salts thereof. The compounds are useful for the treatment and/or prophylaxis of diseases, which are associated with the modulation of CB1 receptors.

nitroalkenes into indoles. Under mild reaction conditions (1 atm carbonmonoxide, 110 °C), palladium catalyzes the reductivecyclization of nitroalkenes to form a putative nitrosoalkene intermediate, which then rearranges to provide 3-arylindoles in high yields. Notably, this novel C–H bond amination takes advantage of carbonmonoxide as an inexpensive stoichiometric reductant and produces carbon dioxide as
