—— | 2-acetamido-6-methylpteridin-4(3H)-one | 19962-30-2 | C9H9N5O2 | 219.203 |
N-(6-甲酰基-4-氧代-1H-蝶啶-2-基)乙酰胺 | N2-acetyl-6-formylpterin | 29769-49-1 | C9H7N5O3 | 233.186 |
6-Aminomethyl-5,6,7,8-tetrahydropterin has been prepared by reduction of 2-acetamido-6-cyanopteridin-4(3H)-one* to 2-acetamido-6-aminomethyl- 5,6,7,8-tetrahydropteridin-4(3H)-one followed by acid hydrolysis. The hitherto undescribed 6-cyanopterin was prepared by careful hydrolysis of the 2-acetamido compound prepared by dehydration of the oxime derived from 2-acetamido-6-formylpteridin-4(3H)-one. The latter was prepared by selenium dioxide oxidation of the methyl compound. Oxidation of 6-aminomethyl-5,6,7,8-tetrahydropterin at neutral pH appears to proceed with significant side-chain loss in Tris buffer but not in phosphate buffer.
