A practical synthesis of a highly functionalized tetrahydropyran DPP-4 inhibitor is described. The asymmetric synthesis relies on three back-to-back Ru-catalyzed reactions. A Ru-catalyzed dynamic kinetic resolution (DKR) reduction establishes two contiguous stereogenic centers in one operation. A unique dihydropyran ring is efficiently constructed through a preferred Ru-catalyzed cycloisomerization. Hydroboration followed by a Ru-catalyzed oxidation affords the desired functionalized pyranone core scaffold. Finally, stereoselective reductive amination and subsequent acidic deprotection afford the desired, potent DPP-4 inhibitor in 25% overall yield. (Chemical Equation Presented).

Synthesis of [14C]omarigliptin

An efficient synthesis for [14C]Omarigliptin (MK-3102) is described. The initial synthesis of a key 14C-pyrazole moiety did not work due to the lack of stability of 14C-DMF-DMA reagent. Thus, a new radiolabeled synthon, 14C-biphenylmethylformate, was synthesized from 14C-sodium formate in one step in 92% yield and successfully used in construction of the key 14C-pyrazole moiety. Regioselective N-sulfonation of the pyrazole moiety was achieved through a dehydration-sulfonation-isomerization sequence. [14C]MK 3102 was synthesized in five steps from 14C-biphenylmethylformate with 25% overall yield.
