which was then converted to the ureaderivative 5 and cyclopropylamine 7 by Curtiusrearrangement of an acyl azide. The urea intermediate 5 was utilized to prepare thymine 10, uracil 11, and cytosine 14 derivatives. The hypoxanthine, adenine, and guanine nucleosides 21, 22, and 24 were synthesized from the amino intermediate 7.
