Abstract
An efficient one-pot approach to access functionalized 3,4-dihydro-[1,3]oxazin-2-one skeletons has been developed through BF3·Et2O-mediated addition-cyclization of ynamides and N-Boc phenylsulfones. The metal-free catalytic method exhibits good functional group compatibility. This study provides a practical new method for the synthesis of oxazinone skeletons.
