We report an efficient palladium-catalyzed approach to the synthesis of benzoxazole derivatives via sequential heteroarylation/acylation reaction of iodobenzenes. Three readily available starting materials, iodobenzenes, anhydrides, and benzoxazoles, were smoothly coupled to form new C–C bonds at the ortho and ipso positions of the iodobenzenes to afford 2-heteroaryl-3-acylbenzene derivatives in good
An efficient protocol was developed for Pd-catalyzed direct C H bond acylation by cross-dehydrogenative-coupling of arylbenzothiazoles and benzylic alcohols using tert-butyl hydroperoxide (TBHP) as the oxidant. The acylation reactions exhibit good reactivities and excellent regioselectivity. (C) 2013 Elsevier Ltd. All rights reserved.
