Provided herein are non-peptide GLP-1 receptor modulator compounds, for example, of Formula (I), pharmaceutical compositions comprising such compounds, and processes of preparation thereof. Also provided are methods of their use for the treatment of a metabolic disorder.
A simple nickel catalyst converts terminal alkynes and formic acid to α-chiral carboxylic acids in high enantioselectivity. The reaction proceeds via the hydrocarboxylation of alkynes and enantioselective transfer hydrogenation of acrylic acids.

Allenylesters R1R2C=C=C(H)C(O)R (R = OMe) or amides (R = NEt2) are formed with excellent selectivities and in good yields by carbonylation of propynyl and allenyl halides at 1–20 bar CO pressure in benzene, in the presence of MeOH or HNEt2 and 1% of Pd(PPh3)4 or trans-Me2C=C=C(H)Pd(PPh3)2Br. Possible organometallic intermediates are discussed.

The synthesis of nonconjugated cyclohex-3-enones via the regiodivergent cobalt-catalysed Diels-Alder reactions of 2-(trimethylsilyloxy)buta-1,3-diene with alkynes and hydrolysis of the dihydroaromatic intermediates is described. The application of bidentate phosphine ligands versus pyridine-imine ligands led to the regioselective formation of one out of the two possible regioisomeric products when

Mononuclear coppercomplexes modified with tridentate tris(N-heterocycliccarbene) (triscarbene) ligands are synthesized. The structures of the copper–triscarbene complexes are characterized using X-ray crystallography, X-ray absorption near edge structure (XANES), and extended X-ray absorption fine structure (EXAFS) analyses. These copper–triscarbene complexes are utilized for the cycloaddition of
