  tert-Butyl Peroxybenzoate-Promoted α-Methylation of 1,3-Dicarbonyl Compounds

  摘要：

  A tert-butyl peroxybenzoate (TBPB)-promoted direct a-methylation of 1,3-dicarbonyl compounds has been developed, providing alpha-methyl derivatives in moderate to good yields. In this procedure, TBPB plays a dual role, serving as both the methyl source and radical initiator. This work represents a key complement to the traditional alpha-methylation of 1,3-dicarbonyl compounds using methyl iodide.

  The reaction of tris(triphenylphosphine)rhodium chloride [RhCl(PPh3)3] with diethylzinc (Et2Zn) easily afforded a rhodium-hydride complex that effects the 1,4-reduction of α,β-unsaturated esters to give rhodium enolates. Formation of the rhodium enolate is followed by transmetalation with the zinc species to give a Reformatsky-type reagent, and this reacts with various acid chlorides at the α-position

  三（三苯基膦）氯化铑[RhCl（PPh 3）3 ]与二乙基锌（Et 2 Zn）的反应容易得到氢化铑络合物，该络合物可实现α，β-不饱和酯的1,4-还原，从而得到烯醇铑。 。形成烯醇铑后，与锌物种进行金属转移以形成Reformatsky型试剂，该试剂在α位与各种酰氯反应生成β-酮酸酯。Reformatsky型试剂还可以与各种亲电子试剂（如醛，酮和酸酐）反应，得到相应的产物，其中亲电试剂在α，β-不饱和酯的α-位被还原性引入。
