1-Alkoxy-5-alkyluracils 2a-f have been prepared by the reaction of 2-alkyl-3-methoxyacryloyl isocyanates 8a-b with alkoxyamines 9a-c followed by cyclization of the resulting N-alkoxy-N'-(2-alkyl-3-methoxyacryloyl)ureas 10a-f. The isocyanates 8a-b were prepared from ethyl 2-alkylacrylates 3a-b in 5 steps.
