2-Carbamoyl-6-éthyl-3-phényl-2,3,5,6-tétrahydro-1,4,2-dioxazine

Abstract

The structure of the title compound, C12H16N2O3, has been established by X‐ray crystallographic study. The dioxazocine ring has a chair conformation and a hydrogen bond links the O and N atoms of two adjacent carbamoyl groups.
