## Abstract Derivatives of the unknown 2โaminoโ6__H__โ1,3โoxazinโ6โone **2** have been synthesized for the first time in two steps and in excellent yields, starting from __N__โcyanocarbonimidates **3a**โ**c** and cyanoacetates. The structures of **2a**โ**c** are assigned by NMRโspectroscopic method
## Abstract 1,3โOxazolidinโ4โones and 1,3โoxazinโ4โones were synthesized by formal cyclocondensation of imines with ฮฑโ or ฮฒโhydroxy acids.
A novel and facile synthesis of 6-substituted chiral N-aryl-l,3-oxazin-2-one derivatives has been achieved starting from readily available (A)-aspartic acid.
