## Abstract Derivatives of the unknown 2βaminoβ6__H__β1,3βoxazinβ6βone **2** have been synthesized for the first time in two steps and in excellent yields, starting from __N__βcyanocarbonimidates **3a**β**c** and cyanoacetates. The structures of **2a**β**c** are assigned by NMRβspectroscopic method
