日期:——
A TMSCl-mediated cascade annulation of isatin-derived propargylicalcohols for the synthesis of 2-substituted 3-chlorobenzofurans is now reported. Mechanistic investigations showed that this proceeded through a sequential Meyer–Schuster rearrangement/nucleophilic addition/intramolecular annulation. TMSCl not only acts as a promoter, but also acts as a chlorine source in this protocol.

employed as the electrophiles for the organocatalyticMichael addition/cyclization cascade reaction with versatile 3-isothiocyanato oxindoles. Chiral bifunctional organocatalyst was appropriate for this enantioselective transformation to afford a variety of novel spirooxindoles, possessing a spirocyclic stereocenter adjacent to the aromatic ring, via asymmetricdouble arylation. These synthesized spirooxindoles

An efficient method for the iodine-catalyzed oxidation of N-substituted indoles by using chloramine-B under mild reaction conditions was explored. This reaction was found to be tolerant to a variety of functional groups and provided the corresponding isatins in moderate to excellent yields. In addition, application of this method to the one-pot synthesis of 3-hydroxyoxindole and N-methylisatin oxime
