## Abstract The ^1^H NMR spectra of thirteen dihydro‐1,2‐oxazine derivatives are reported. Spin decoupling allows analysis of the spectra, features of which include homoallylic couplings of +2 to +2·5 Hz, allylic couplings of −1·5 to −1·7 Hz and vicinal couplings across __sp__^2^ to __sp__^3^ carbo
## Abstract Novel pyridazino[4,5‐__b__][1,4]oxazine‐3,5‐diones were synthesized from __N__‐[2‐(3,4‐dimethoxyphenyl)‐ethyl]‐2‐chloroacetamide (or 2‐chloropropanamide) and 1‐alkyl‐5‐halo‐4‐hydroxypyridazin‐6‐ones in good yield.
