An easy and efficient synthesis of 3-alkyluracils is described. Thus, BOC-protection at N-1 of uracil permits selective alkylation at N-3. This protecting group can be removed under very mild conditions.
Direct N<sub>3</sub> Alkylation of Uracil and Derivatives via <sub>n1</sub>-[2-(trimethylsilyl)ethoxymethyl] Protection
Protection at N1 position of uracil and uracil analogs as 2-(trimethylsilyl)ethoxymethyl derivatives permits the clean alkylation at N3. These protected uracils are quite stable in a wide range of pH.
