Herein, nickel-catalyzed synthesis of polyarylcarbazole through sequential C-H bond activations has been described. Regioselective indole C2/C3 functionalization has been achieved in the presence of indole C7-H, which is quite challenging. In addition, this approach also gives easy access to building a heteropolycyclic motif through C6/C7 C-H functionalization of indoline. This methodology is not limited to aromatic internal alkynes as coupling partners; aliphatic alkynes have also shown good tolerance. Notably, during the optimization the catalytic enhancement with sodium iodide as an additive has been observed. We have also studied the photophysical properties of these highly conjugated molecules.

Described herein are rhenium-catalyzed [3+2] annulations of N-carbamoyl indoles with alkynes via C?H/C?N bond cleavage, which provide rapid access to fused-ring pyrroloindolone derivatives. For the first time, the weakly coordinating O-directing group was successfully employed in rhenium-catalyzed C?H activation reactions, enabled by the unique catalytic trio of Re2(CO)10, Me2Zn and ZnCl2. Mechanistic studies revealed that aminozinc species plays an important role in the reaction. Based on the mechanistic understanding, a more powerful catalytic trio of Re2(CO)10, [MeZnNPh2]2 and Zn(OTf)2 was devised and applied successfully in the [4+2] annulations of indolines and alkynes affording pyrroloquinolinone derivatives.

We disclose herein a photocatalytic difluoroalkylation and cyclization cascade reaction of N-(but-2-enoyl)indoles with broad substrate scopes in up to 90% isolated yield. This method provides sustainable and efficient access to synthesize difluoroalkylated pyrrolo[1,2-a]indoles with a quaternary carbon center under mild conditions.

GPR119 has emerged as an attractive target for anti-diabetic agents. We identified a structurally novel GPR119 agonist 22c that carries a 5-(methylsulfonyl)indoline motif as an early lead compound. To generate more potent compounds of this series, structural modifications were performed mainly to the central alkylene spacer. Installation of a carbonyl group and a methyl group on this spacer significantly enhanced agonistic activity, resulting in the identification of 2-[1-(5-ethylpyrimidin-2-yl)piperidin-4-yl]propyl 7-fluoro-5-(methylsulfonyl)-2,3-dihydro-1H-indole-1-carboxylate (20). To further expand the chemical series of indoline-based GPR119 agonists, several heterocyclic core systems were introduced as surrogates of the carbamate spacer that mimic the presumed active conformation. This approach successfully produced an indolinylpyrimidine derivative 37, 5-(methylsulfonyl)-1-[6-({1-[3-(propan-2- yl)-1,2,4-oxadiazol-5-yl]piperidin-4-yl}oxy)pyrimidin-4-yl]-2, 3-dihydro-1H-indole, which has potent GPR119 agonist activity. In rat oral glucose tolerance tests, these two indoline-based compounds effectively lowered plasma glucose excursion and glucose-dependent insulin secretion after oral administration.

A novel series of N-linked β-d-xylosides were synthesized and evaluated for inhibitory activity against sodium-dependent glucose cotransporter 2 (SGLT2) in a cell-based assay. Of these, the 4-chloro-3-(4-cyclopropylbenzyl) -1-(β-d-xylopyranosyl)-1H-indole 19m was found to be the most potent inhibitor, with an EC50 value similar to that of the natural SGLT2 inhibitor phlorizin. Further studies in Sprague-Dawley (SD) rats indicated that 19m significantly increased urine glucose excretion in a dose-dependent manner with oral administration. The antihyperglycemic effect of 19m was also observed in streptozotocin (STZ) induced diabetic SD rats. These results described here are a good starting point for further investigations into N-glycoside SGLT2 inhibitors.
