Palladium-catalyzed Csp<sup>2</sup>–H carbonylation of aromatic oximes: selective access to benzo[d][1,2]oxazin-1-ones and 3-methyleneisoindolin-1-ones
A selective palladium-catalyzed carbonylation of Csp2–H bonds with aromatic oximes for the synthesis of benzo[d][1,2]oxazin-1-ones and 3-methyleneisoindolin-1-ones has been developed.

applying an oximeacetate block as the sole component via oxidative homo/cross-coupling catalyzed by Cu(I) was developed. This strategy provides a straightforward method to produce a series of substituted 2H-imidazoles in moderate to excellent yields. The transformation process is straightforward to operate and is considered as a readily available catalytic system exhibiting good substrate compatibility

Reductive acetylation of ketoximes to give the corresponding acyl enamides can be achieved by using 1-3 mol % of [RuCl2(p-cymene)](2) as the catalyst in the presence of KI as the reducing agent in high yields. This procedure has been applied to synthesize N-[1-(1,3-benzodioxol-5-yl)-1-butenyl]acetamide (6), which is the intermediate for the synthesis of DMP 777, an inhibitor of leukocyte elastase.
