In a patent, introducing its new discovery.

A readily available intermediate obtained from d-arabinose was identified as a versatile starting material for the stereoselective synthesis of C-pentopyranosides in one pot. For two of the C-pentopyranosides, subsequent epoxide ring formation and a regioselective opening process was proven to be a robust approach to 3-deoxy C-pentopyranosides in two to four steps. A key intermediate used in the preparation of omarigliptin was obtained in four steps. Most of the conversions were high-yielding and proceeded with high selectivities on a multigram scale.

Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In homogeneous catalysis, catalysts are in the same phase as the reactants.951127-25-6, C16H19F2NO4. A document type is Article, introducing its new discovery., Synthetic Route of 951127-25-6

A series of novel tri-2,3,5-substituted tetrahydropyran analogs were synthesized and evaluated as inhibitors of dipeptidyl peptidase IV (DPP-4) for the treatment of type 2 diabetes. Optimization of the series provided inhibitors with good DPP-4 potency and selectivity over other peptidases (QPP, DPP8, and FAP). Compound 23, which is very potent, selective, efficacious in the diabetes PD model, and has an excellent pharmacokinetic profile, is selected as a clinical candidate.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. 951127-25-6, Name is tert-Butyl ((2R,3S)-2-(2,5-difluorophenyl)-5-oxotetrahydro-2H-pyran-3-yl)carbamate, molecular formula is C16H19F2NO4. In a Article，once mentioned of 951127-25-6, Computed Properties of C16H19F2NO4

Development of a convergent synthesis of omarigliptin (MK-3102) suitable for commercial manufacture is described. The target molecule is assembled through a diastereoselective reductive amination of a highly functionalized pyranone with a mesylated pyrazole followed by deprotection of a Boc group. The synthesis of the pyranone relies on three Ru-catalyzed reactions: (1) a DKR reduction of a rac-alpha-aminoketone to set the two contiguous stereogenic centers, (2) a cycloisomerization of a bis-homopropargylic alcohol to a dihydropyran, and, finally, (3) a Ru-catalyzed oxidation of a pyranol to the desired pyranone. The regioselective synthesis of a N-Boc-1-mesyl pyrazole fragment was achieved via base-promoted mesyl group isomerization to afford 30:1 selectivity. A highlight of the endgame process development is telescoping a Boc deprotection and reductive amination followed by direct crystallization of the penultimate from the reaction mixture. This avoids handling of an unstable, mutagenic 1-mesylpyrazole BSA salt used in the earlier multikilogram deliveries and improves the overall diastereoselectivity and efficiency of the route.
