secondary C-Hbonds, which are adjacent to an oxygen or nitrogen atom on one side, and benzylic or adjacent to a carbonyl group on the other side. A variety of valuable fused heterocycles were obtained from easily accessible ortho-bromophenol and aniline precursors. The second C-H bond cleavage was successfully replaced with carbonyl insertion to generate other types of C(sp3 )-C(sp3 ) bonds.

ylic acid amides (ATCAA). The antiproliferative activity of the SMART agents against melanoma and prostate cancer cells was improved from μM to low nM range compared with the ATCAA series. The structure−activityrelationship was discussed from modifications of “A”, “B”, and “C” rings and the linker. Preliminary mechanism of action studies indicated that these compounds exert their anticancer activity
Described here is the first example of a rhodium‐catalyzed carboacylation/aromatization cascade of a C=O bond by C−Cactivation. In this transformation, a reactive rhodaindanone complex is regioselectively generated and adds across a C=O bond with subsequent elimination, thus providing a unique strategy to access a multisubstituted benzofuran scaffold. A diverse range of benzofuran analogues were obtained
