Synthesis of 2-Amino-4-hydroxyl-6-hydroxymethyl-5,6,7,8-tetrahydropyrido[3,2-d]pyrimidine from 2-Amino-4-hydroxyl-6-methylpyrimidine

[摘要]：The synthesis of 2-amino-4-hydroxyl-6-hydroxymethyl-5,6,7,8-tetrahydropyrido[3,2-d]pyrim idine 3 is described from 2-amino-6-methyluracil 4 through the crucial step of 2-pivaloyl protecting and cyclization. The assignment of the structure of 3 was performed by its spectral data, the H-1 NMR, C-13 NMR, gHMQC, and HRMS spectra.
