  .alpha.-Keto Amides and 1,2-Diketones from N,N'-Dimethoxy-N,N'-dimethylethanediamide. A Synthetic and Mechanistic Investigation

  摘要：

  N,N'-Dimethoxy-N,N'-dimethylethanediamide (1), a 1,2-dicarbonyl synthon prepared from oxalyl chloride, undergoes nucleophilic displacements with Grignard reagents to provide alpha-keto amides 2-12 in 28-90% yields. The synthon also undergoes double nucleophilic displacements with organolithium reagents to furnish symmetrical 1,2-diketones 15-23 in 15-84% yields. A mechanism accounting for all the products from the reaction of 1 with nucleophiles has been proposed. Several control experiments were carried out to support the proposed mechanism.

  N,N'-Dimethoxy-N,N'-dimethylethanediamide on treatment with one to two equivalents of alkyl, aryl, and benzyl Grignard reagents provide alpha-oxo-N-methoxy-N-methylamides in good to excellent yields and on reaction with excess aryllithiums furnish moderate to good yields of symmetrical 1,2-diarylketones.
