Convenient Synthesis of 3-Alkoxy-3-aryloxindoles by Intramolecular Arylation of Mandelic Amides
摘要:
Medicinally important 3-alkoxy-3-aryloxindoles are conveniently prepared by the rapid microwave-promoted palladium-catalyzed intramolecular enolate arylation of mandelate-derived anilides.

The Pd-catalysed asymmetric intramolecular alpha-arylation of amide enolates containing heteroatom substituents gives chiral 3-alkoxy or 3-aminooxindoles in high yield and with enantioselectivities up to 97% ee when a new chiralN-heterocycliccarbeneligand is used.
