2-氨基-5,6,7,8-四氢-1H-蝶啶-4-酮 | 5,6,7,8-tetrahydropterin | 1008-35-1 | C6H9N5O | 167.17 |
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.
