excellent yields. A one‐pot, unsymmetrical, twofold C−H functionalization involving intramolecular C−C and intermolecular C−C/C−N bond formations is successfully demonstrated by using a single set of catalytic reaction conditions, which is unprecedented thus far. A novel isoquinolone‐bearing dihydrobenzofuran is constructed through an unsymmetrical twofold C−H functionalization.

5HT3 receptor antagonist identified via extensive SARstudies was endo-5-chloro-2,3-dihydro-2,2-dimethyl-N-(8-methyl-8-azabicyclo[3.2.1]oc t- 3-yl)-7-benzofurancarboxamide (Z)-2-butenedioate (zatosetron maleate). The 7-carbamyl regiochemistry, dimethyl substitution, chloro substituent, and endo stereochemistry were all crucial elements of the SAR. Zatosetron maleate was a potentantagonist of 5HT-induced

Biologically interesting fused oligocyclic lactams have been prepared via an intramolecular redox-neutral cyclization process. By the proper choice of the substrates with a wide variety of tethered olefins, the less favored CâH bond can be activated and functionalized. This CâH activation proceeds under mild conditions, obviates the need for external oxidants, and displays a broad scope with respect to the substituents.
