## Abstract Methyl (Z)‐2‐acetylamino‐3‐dimethylaminopropenoate (3) was prepared from __N__‐acetylglycine (1), which was converted with __N,N__‐dimethylformamide and phosphorus oxychloride into 4‐dimethylaminomethylene‐2‐methyl‐5(4__H__)‐oxazolone (2), followed by treatment with methanol in the pres
Synthesis of 3-Hydroxy and 3-Amino 2-Substituted N-Heterocycles via Enamine Oxidation and Aziridination. -Usual asymmetric epoxidation of the N-sulfonyl heterocyclic enamines (I) followed by methanolysis results in formation of 2,3-dihydroxy derivatives. Only diol derivatives are also obtained unde
