Starting from phenethanolamine aniline leads 3a and 3b, we have identified a series of functionally potent and selective β3 adrenergic receptor (AR) agonists containing acylsulfonamide, sulfonylsulfonamide, or sulfonylurea groups within the ani

The insertion of an aryne into a C-S bond can suppress the addition of an S nucleophile to the aryne in the presence of palladium. Catalyzed by Pd(OAc)2, a wide range of α-carbamoyl ketene dithioacetals readily react with arynes to selectively afford functionalized 2-quinolinones in high yields under neutral reaction conditions by a C-S activation/aryne insertion/intramolecular coupling sequence. The attractive feature of the new strategy also lies in the versatile transformations of the alkythio-substituted quinolinone products. Within range: Under palladium catalysis a wide range of α-carbamoyl ketene dithioacetals readily react with arynes to selectively afford 2-quinolinones in high yields under neutral reaction conditions by the title sequence (see scheme). An attractive feature of the new strategy also lies in the versatile transformations of the alkylthio-substituted quinolinones.
