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.
Air-Stable Secondary Phosphine Oxide as Preligand for Palladium-Catalyzed Intramolecular α-Arylations with Chloroarenes
摘要:
A palladium catalyst derived from air-stable secondary phosphine oxide (1-Ad)(2)P(O)H enabled efficient intramolecular alpha-arylations of amides with aryl chlorides, which allowed for the synthesis of diversely substituted (aza)oxindoles.
