Synthesis of Oxindole Derivatives via Intramolecular C–H Insertion of Diazoamides Using Ru(II)-Pheox Catalyst

This work presented the efficient intramolecular aromatic C–H insertion of diazoacetamide. The 1a–1o diazo compounds (except for 1k) were converted into their corresponding oxindoles via an intramolecular C–H insertion reaction in the presence of a Ru catalyst. The Ru-Pheox catalyst was shown to be highly efficient in this transformation in terms of the regioselectivity, producing the desired products in excellent yield (99%). The efficiency of the Ru catalyst reached 580 (TON) and 156 min?1 (TOF).

Synthesis of 2-Oxindoles from Substituted Indoles by Hypervalent-Iodine Oxidation

A practical conversion of indoles into the corresponding 2-oxindoles is achieved efficiently using a hypervalent iodine reagent. This oxidation is amenable to different substituted indoles, and allows the synthesis of a wide range of synthetically valuable substituted 2-oxindoles in up to 90 % yield. Furthermore, Ropinirole, a drug used to alleviate the symptoms of Parkinson's disease, was synthesized in three steps in an overall yield of 44 % using this method.

Synthesis of spiro[furan-3,3′-indolin]-2′-ones by PET-catalyzed [3+2] reactions of spiro[indoline-3,2′-oxiran]-2-ones with electron-rich olefins

An efficient procedure for the synthesis of spiro[furan-3,3′-indolin] -2-ones and dispiro[cycloalkane-1,2′-furan-3′,3″-indolin]- 2″-ones has been achieved in high yields and stereoselectivity by photoinduced electron transfer-catalyzed [3+2] reactions of substituted spiro[indoline-3,2′-oxiran]-2-ones with olefins. The reactions proceed by ring opening of spiro[indoline-3,2′-oxiran]-2-ones via C β-O bond cleavage and subsequent cycloaddition with olefins by using 2,4,6-triphenylpyrylium tetarfluoroborate (TPT) as a sensitizer.

Irreversible Nek2 kinase inhibitors with cellular activity

A structure-based approach was used to design irreversible, cysteine-targeted inhibitors of the human centrosomal kinase, Nek2. Potent inhibition of Nek2 kinase activity in biochemical and cell-based assays required a noncatalytic cysteine residue (Cys22), located near the glycine-rich loop in a subset of human kinases. Elaboration of an oxindole scaffold led to our most selective compound, oxindole propynamide 16 (JH295). Propynamide 16 irreversibly inhibited cellular Nek2 without affecting the mitotic kinases, Cdk1, Aurora B, or Plk1. Moreover, 16 did not perturb bipolar spindle assembly or the spindle assembly checkpoint. To our knowledge, 16 is the first small molecule shown to inactivate Nek2 kinase activity in cells.
