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 Nβcyanocarbonimidates 3aβc and cyanoacetates. The structures of 2aβc are assigned by NMRβspectroscopic methods and corroborated by an Xβray structure analysis of 2c.
