Structure Determination of Tunicaminyl Uracil, a Degradation Product of Tunicamycin

Abstract

Tunicaminyl uracil, C₁₅H₂₃N₃O₁₀, was obtained by the hydrolysis of tunicamycin with 3 _N HCl at 100° for 3hr. By a combination of chemical and spectrometric methods, its structure was determined to be 1-β-(10'-amino-6', 10'-dideoxy-L-galacto-D-allo-undecodialdo-7', 11'-pyranose-1', 4'-furanosyl)-uracil (I).
