## Abstract Derivatives of the unknown 2‐amino‐6__H__‐1,3‐oxazin‐6‐one **2** have been synthesized for the first time in two steps and in excellent yields, starting from __N__‐cyanocarbonimidates **3a**–**c** and cyanoacetates. The structures of **2a**–**c** are assigned by NMR‐spectroscopic method
