PPARgamma activity although binding affinity to PPARgamma may be maintained. A particularly promising set of analogues is the anthranilic acidesters 63-66 in which the phenyl ring in the 2-benzoyl group of 1 and 2 has been replaced by an alkoxy group. In particular, (S)-2-(1-carboxy-2- inverted question mark4-[2-(5-methyl-2-phenyloxazol-4-yl)ethoxy]phen yl inverted question mark ethylamino)benzoic acid

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

from the reaction of propargyl alcohol-tethered alkylidenecyclopropanes with iodine. The reaction proceeded through an iodination-initiated cascade intramolecular enyne cyclization and electrophilic aromatic substitution reaction process in 1,2-dichloroethane upon heating, giving desired spirocyclic products in moderate to excellent yields. Further transformation of the obtained products has also been
