A chemoselective S-arylation reaction of thio-oxindoles with arynes is presented. The reaction was performed under mild conditions and provided a straightforward synthesis of 2-(arylthio)indolenines in good to excellent yields. Besides, this simple operat

A nickel(ii) catalyzed enantioselective thio-Claisen rearrangement of α-diazo pyrazoleamides with thioindoles was realized with modified chiral N,N′-dioxide ligands, affording a variety of C3-substituted indole derivatives in high yields (up to 95%) with excellent enantioselectivities (up to 96% ee) under mild reaction conditions. A possible transition state model was proposed based on previous reports and the X-ray crystal structure of the catalyst.

Thieno[2,3-b]indole derivatives were efficiently prepared via the reaction of 1,3-dihydro-2H-indole-2-thiones with α-bromo-substituted ketones or aldehydes and in the presence of Et3N (Scheme 2 and Table). The reaction took place under very mil
Concise syntheses of the cruciferous phytoalexins brassilexin, sinalexin, wasalexins, and analogues: Expanding the scope of the Vilsmeier formylation

(Chemical Equation Presented) Efficient syntheses of the phytoalexins brassilexin, sinalexin, and analogues are demonstrated through the application of the Vilsmeier formylation to indoline-2-thiones followed by a new aqueous ammonia workup procedure. Similarly, a very concise two-pot synthesis of the phytoalexins wasalexins using sequential formylation-amination of indolin-2-ones is described. Remarkably, this novel aqueous ammonia workup allows the sequential one-pot formylation-amination, expanding substantially the scope of the Vilsmeier formylation of both indoline-2-thiones and indolin-2-ones. The examination of the formylation-amination reaction and optimization of conditions, as well as the syntheses and antifungal activities of several brassilexin analogues, are reported.
