Abstract
N,”-Dimethoxy-N,”-dimethylethanediamide (11, a 1, 2-dicarbonyl synthon prepared from oxalyl chloride, undergoes nucleophilic displacements with Grignard reagents to provide a- 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 ...
