3-(Diarylmethylene)oxindoles have been synthesized from propiolamidoaryl triflate utilizing a palladium-catalyzed one-pot reaction consisting of three successive reactions: Sonogashira, Heck, and Suzuki-Miyaura. This method allows for the production of a complex skeleton of 3-(diarylmethylene)oxindole from propiolamidoaryl triflate using a commercially available aryl iodide and arylboronic acid in a simple and efficient way with moderate yield and stereoselectivity.

We developed a rapid and efficient microwave-assisted tandem reaction for the synthesis of 3-(diarylmethylene)oxindoles. Three palladium-catalyzedreactions (Sonogashira, Heck, and Suzuki–Miyaura reactions) were combined under microwave irradiation conditions to produce 3-(diarylmethylene)oxindoles from simple propiolamides, aryliodides, and arylboronic acids. The addition of Ag 3 PO 4 enhanced the
我们开发了一种快速有效的微波辅助串联反应,用于合成 3-(二芳基亚甲基)羟吲哚。三个钯催化的反应(Sonogashira、Heck 和 Suzuki-Miyaura 反应)在微波辐射条件下结合,从简单的丙酰胺、芳基碘和芳基硼酸生产 3-(二芳基亚甲基)羟吲哚。Ag 3 PO 4 的加入显着提高了串联反应的产率和立体选择性。

reactions (Sonogashira, Heck and Suzuki-Miyaura reactions), a more efficient domino multicomponent method has been successfully developed to access a wide variety of 3-(diarylmethylene)oxindoles. Microwave irradiation and use of a silver salt were the most important factors to achieve high yields and stereoselectivity.

2-oxindoles using diaryl methanols in the absence of an acceptor. A wide array of symmetrical and unsymmetrical diaryl methanols undergoes dehydrogenative coupling with 2-oxindole selectively to generate various substituted 3-(diphenylmethylene)indolin-2-one derivatives in good yields and produces environmentally benign by-products, H2 and H2O. This methodology was successfully applied for the synthesis of
