Copper-catalyzed domino coupling reaction: An efficient method to synthesize oxindoles
Hsieh, Jen-Chieh,Cheng, An-Yi,Fu, Jun-Hao,Kang, Ting-Wei
, p. 6404 - 6409 (2012/09/05)
An efficient and novel procedure for a copper catalyzed domino coupling reaction has been developed, which afforded various oxindoles in good to excellent yields with tolerance of various substituents. In addition, this method could be applied to synthesize horsfiline and coerulescine in few steps with high total yields. The Royal Society of Chemistry 2012.
Heterocyclic Aromatic Anions with 4n + 2 ?-Electrons
Bordwell, Frederick G.,Fried, Herbert E.
, p. 4218 - 4223 (2007/10/02)
Equilibrium acidities in DMSO for several cyclic carboxamides, thiocarboxamides, esters, and sulfones that form anions possessing 4n + 2 electrons have been measured.Aromatic stabilization energies (ASEs) for these anions have been estimated by comparing
REGIOSELECTIVE C-3 ALKYLATIONS OF OXINDOLE DIANION
Kende, Andrew, S.,Hodges, John C.
, p. 1 - 10 (2007/10/02)
Oxindole is converted to its dianion by treatment with two equivalents each of n-BuLi and TMEDA.Alkylations with a number of common electrophiles define the scope of synthetically useful tramsformations leading to 3-monosubstituted and 3,3-disubstituted o
