Pteridine, VIII. Über 4.6‐ und 4.7‐Dihydroxy‐pteridine
Chemische Berichte, 1959AbstractEine vereinfachte Darstellungsmethode des 4.7‐Dihydroxy‐pteridins wird beschrieben. Das 4.5‐Diamino‐6‐oxo‐dihydropyrimidin und sein 1‐Methylderivat zeigen bei Pteridinsynthesen mit Glyoxylsäureäthylester‐halbacetal und Mesoxalsäure ein den allgemein gültigen Orientierungsregeln entgegengesetztes Verhalten.
