A new protocol to synthesize 1,2‐dihydrocyclobuta[b]quinoline derivatives from isocyanophenyl‐substituted methylenecyclopropanes via a formal insertion of isocyanide carbon into a C−C bond has been developed. The reaction proceeds smoothly in the presence of silver carbonate (5 mol%) upon heating in a highly atom economic manner and exhibits broad substrate scope, giving the desired products in moderate

A series of substituted derivatives of 2-amino-3-benzoylphenylaceticacid (amfenac) has been synthesized and evaluated for antiinflammatory, analgesic, and cyclooxygenase inhibiting activity. Several derivatives including 157 (4'-chloro), 158 (4'-bromo), and 182 (5-chloro, 4'-bromo) were more potent than indomethacin in these assays.

A new visible‐light‐induced trifluoromethylation of isonitrile‐substituted methylenecyclopropanes is developed. A range of substituted 6‐(trifluoromethyl)‐7,8‐dihydrobenzo[k]phenanthridine derivatives are readily furnished by this newly developed tandem reaction with moderate to good yields. This reaction allows the direct formation of two six‐membered rings and three new C−C bonds, including the C−CF3
