Oxidative synthesis of benzo[1,4]oxazines from α-branched primary amines and ortho-benzoquinones

The efficient oxidative construction of benzo[1,4]oxazines from simple α-branched amines and ortho-benzoquinones is reported. The procedure pivots on a triethylamine and iodine mediated oxidative ring closure from the ketimine intermediate formed upon their condensation. This reaction was shown to t...
