6-Polyhydroxyalkylpteridines are synthesised by oxidation of the corresponding pyrano[3,2-g]pteridines, the latter ones having been obtained by condensation between 5,6-diaminopyrimidines 1a,b and phenylhydra-zones 2a-e. The relative configuration at the chiral centers of the pyrano[3,2-g]pteridines has been determined by nmr study and X-ray analysis. The anti-AIDS activity of several of these compounds
通过氧化相应的吡喃并[3,2- g ]哌啶来合成6-多羟基烷基哌啶,后者是通过5,6-二氨基嘧啶1a,b和苯并a区2a-e之间的缩合而获得的。吡喃并[3,2- g ]蝶啶的手性中心的相对构型已通过nmr研究和X射线分析确定。已经测试了其中几种化合物的抗艾滋病活性。

Studies on Biologically Active Pteridines. IV. Synthesis of Several Biopterin Derivatives as an Antigen in Radioimmunoassay for Biopterin
The synthesis of biopterin, D(and L)-erythro-neopterins, and their derivatives having a substituent at the 2-amino group via the 2-methylthio analogues is described. The 2-(methylthio)pteridines were synthesized by condensation of 4,5-diamino-6-hydroxy-2-(methylthio)pyrimidine with 5-deoxy-L-arabinose and D(and L)-arabinose phenylhydrazones, followed by oxidation with K3[Fe(CN)6] and O2 in the presence
