  PhI(OAc)₂-Mediated Intramolecular Oxidative Aryl-Aldehyde Csp²–Csp² Bond Formation: Metal-Free Synthesis of Acridone Derivatives

  摘要：

  A metal-free protocol for direct aryl-aldehyde Csp(2)-Csp(2) bond formation via a PhI(OAc)2-mediated intramolecular cross-dehydrogenative coupling (CDC) of various 2-(N-arylamino)aldehydes was developed. The novel methodology requires no need of preactivation of the aldehyde group, is applicable to a large variety of functionalized substrates, and most of all provides a convenient approach to the construction of biologically important acridone derivatives.

  An efficient synthesis of a diverse set of 10-methylacridin-9(10H)-ones from 2-(methylamino)benzophenones has been developed. The reaction proceeds though Cu-catalyzed intramolecular aromatic C–H amination by using O2 as the sole oxidant to provide the desired products in moderate to good yields. In addition, 2-allylamino- and 2-(benzylamino)benzophenones as well as unprotected substrates can also

  A novel method has been developed for the synthesis of substituted N-methylacridones from 2-(N-methyl-N-phenylamino)benzaldehydes via dehydrogenative cyclization. This transformation involves two primary processes: the aldehyde first coordinates with Sc(OTf)(3) and induces the aromatic electrophilic substitution (SEAr) reaction to form the active intermediate N-methyl-acridin-9-ol, which is then quickly oxidized in situ to afford the acridones. Furthermore, the procedure involved is both environmental friendly and atom efficient; H2O is the only byproduct in this reaction.
