An unprecedented ring expansion reaction of indolin-2-ones with alkynyl ketones under transition-metal-free conditions has been developed. Base-promoted selective cleavage of a C-C σ bond of the amide is the key in this process, which provides a straightf
Catalytic enantioselective stereoablative alkylation of 3-halooxindoles: Facile access to oxindoles with c3 all-carbon quaternary stereocenters

From 2 to 1! Racemic tertiary halooxindoles proceed to enantioenriched oxindoles bearing all-carbon quaternary stereocenters as a result of a catalytic enantioselective stereoablative process (see scheme). The application of this procedure allows for the
A mild thermal and acid-catalyzed rearrangement of O-aryl ethers into ortho-hydroxy arenes
Goldberg, Frederick W.,Magnus, Philip,Turnbull, Rachel
, p. 4531 - 4534 (2007/10/03)
(Chemical Equation Presented) An unusual rearrangement of an O-aryl ether to an ortho-hydroxyaryl system was discovered during our studies on the synthesis of diazonamide A. We discuss the exploration of this rearrangement under mild thermal and both Bron
