A highly efficient asymmetric synthesis of the key tetrahydropyranol intermediate of DPP-4 inhibitor omarigliptin (1) is described. The successful development of a protecting-group- and precious-metal-free synthesis was achieved via the discovery of

The dearomatization of a series of electron-deficient nitrogen heterocycles has been achieved through a cobalt-catalyzed asymmetric cyclopropanation reaction. This reaction proceeds with high levels of enantio- and diastereoselectivity to afford uniq

α- and β-substitution of dihydrocinnamates has been shown to increase the biological activity of various drug candidates. Recently, we identified enantio- and diastereopure α-methyl-β-cyclopropyldihydrocinnamates to be important pharmacophores in

We describe the development of (η3-1-tBu-indenyl)2(μ-Cl)2Pd2, a versatile precatalyst scaffold for Pd-catalyzed cross-coupling. Our new system is more active than commercially available (η3-cinnamyl)2(μ-Cl)2Pd2 and is compatible with a range of N

The activity of bis(phosphine) iron dialkyl complexes for the asymmetric hydrogenation of alkenes has been evaluated. High-throughput experimentation was used to identify suitable iron–phosphine combinations using the displacement of pyridine from

A new palladacycle precatalyst ( J009 PreCat ) was designed and synthesized. The precatalyst dramatically improved the yield of a class of extremely challenging cross-coupling reactions between functionalized heteroaryl chlorides and electron-deficie

Lighter Hydrogenation Catalysts Enzymes have evolved to use abundant metals such as iron, cobalt, and nickel for redox catalysis. However, synthetic catalysis has generally relied on the rarer, heavier relatives of these elements: ruthenium, rhodium,

A palladium-catalyzed cross coupling of nitrogen bearing heterocyclic chloromethyl derivatives with aryl and heteroaryl boronic acids has been developed. In almost all cases, highly efficient cross-couplings were observed at ambient temperature, miti
