  4-Bromomethyl-2-chlorooxazole––a versatile oxazole cross-coupling unit for the synthesis of 2,4-disubstituted oxazoles

  摘要：

  The synthesis of the novel oxazole building block, 4-bromomethyl-2-chlorooxazole, and its palladium-catalysed cross-coupling reactions to make a range of 2,4-disubstituted oxazoles, is described. Selectivity for the 4-bromomethyl position is observed, with Stifle coupling effected in good to excellent yields, or Suzuki coupling in moderate yields, to provide a range of 4-substituted-2-chlorooxazoles. Subsequent coupling at the 2-chloro-position can be achieved through either Stille Or Suzuki reactions in excellent yields. (C) 2004 Elsevier Ltd. All rights reserved.

  The palladium-catalyzed coupling of acid chlorides with (E)-1,2-bis(tri-n-butylstannyl)ethene or beta-stannyl enones gives butane-1,4-diones directly by reduction of the intermediate enedicarbonyl intermediate. The double bond conjugated with a single carbonyl group was not significantly reduced. The generality of the method is illustrated by two syntheses of the 1,4-diketone ipomeanine. By performing the reaction at lower temperatures, alpha,beta-unsaturated 1,4-diketones can also be prepared. The reduction of the intermediate alpha,beta-unsaturated 1,4-diketones probably proceeds by insertion of a palladium hydride, formed in situ by reaction of a Pd(II) complex with Bu(3)SnCl, followed by hydrolysis of the intermediate palladium enolate.
