Abstract

A mild and efficient silver-mediated synthesis of 2,3-dihydro-1,3-oxazin-4-ones through a formal [4+2] cycloaddition reaction of aldimines and acylketene intermediates is described. A variety of functionalized and potentially biologically relevant heterocycles have been accessed in moderate to high yields through this process.
