compound library containing the carboxylic acid functional group uncovered a bromophenyl derivative as a moderate potent GPR40 agonist. Chemical elaboration of this bromophenyl led to the discovery of a novel series of GPR40 agonists with submicromolar potency. Among them, 22 and 24 behaved as full agonists when compared to the endogenous GPR40 ligand linolenic acid in a functional Ca+2 flux assay in HEK

1-naphthylamine, and 2-halobenzyl bromides is reported. A variety of tricyclic, tetracyclic, and pentacyclic sultams have been prepared via palladium-catalyzed, ligand-free intramolecularcyclization. Detailed mechanistic studies of the reaction pathway are also described. cyclization - palladium acetate - sulfonamides - sultams

Hitherto unreported 2H-thiopyrano[3,2-c][1]benzopyran-5-ones 6a–f are synthesized regioselectively in 79–85% yields by the thio-Claisen rearrangement of 4-propargylthio[1]benzopyran-2-ones 5a–f. The substrates 5a–f are synthesized by alkylation of hitherto unreported 4-mercaptocoumarins.

and use of an inexpensive readily prepared opticallyactive 1,3-disubstituted allene that may be utilized for enantioselective intramolecular allene/enone photocycloadditions. In addition, we describe novel substrates for intramolecular [2+2] photocycloadditions which substantially expand the scope of the process to include amino- and thio- tethered allene/enones.
