  Silver-Promoted, Palladium-Catalyzed Direct Arylation of Cyclopropanes: Facile Access to Spiro 3,3′-Cyclopropyl Oxindoles

  摘要：

  The Pd-catalyzed, Ag(I)-mediated intramolecular direct arylation of cyclopropane C H bonds is described. Various spiro 3,3'-cyclopropyl oxindoles can be obtained in good to excellent yields from easily accessible 2-bromoanilides. The kinetic isotope effect was determined and epimerization studies were conducted, suggesting that the formation of a putative Pd-enolate is not operative and that the reaction proceeds via a C-H arylation pathway.

  We have demonstrated a Pd(0)-catalyzed Heck/C(sp3)–H activation cascade for the synthesis of spirocyclopropyl oxindoles in high yields from easily accessible ortho-bromoacrylamides. The formation of spirocyclopropyl oxindole is guided by an unconventional four-membered palladacycle through C(sp3)–H activation. The reaction exhibits a wide range of substrate scope and operates efficiently with a mere

  我们已经展示了 Pd(0) 催化的 Heck/C(sp 3 )–H 活化级联，用于从易于获得的邻溴丙烯酰胺中高产率合成螺环丙基羟吲哚。螺环丙基羟吲哚的形成是由非常规四元钯环通过 C(sp 3 )–H 活化引导的。该反应表现出广泛的底物范围，并且仅用 0.5 mol% 的 Pd 催化剂即可有效运行。此外，微波条件的使用有利于反应快速完成。此外，这种螺环丙烷化策略可以与[3 + 2]环加成结合产生螺吡咯烷羟吲哚，为制备(±)-horsfiline和(±)-coerulescine等生物碱提供了有价值的方法。
