6-Amino-6-deoxyfumagillol (5) was synthesized by reductive amination of 6-oxo-6-deoxyfumagillol (4), which was obtained by oxidation of fumagiollol (2). The reduction proceeded stereoselectively by the equatorial attack of hydride and 5 was found to have the same stereochemistry as that of 2. Several derivatives of 5 were prepared and most of them showed anti-angiogenic activity comparable to that of fumagillol derivatives.
6-氨基-6-去氧富马吉洛尔(5)是通过对6-氧-6-去氧富马吉洛尔(4)进行还原胺化合成的,后者是通过氧化富马吉洛尔(2)获得的。还原过程通过氢的赤道攻击进行立体选择性反应,发现5的立体化学与2相同。合成了几种5的衍生物,其中大多数显示出与富马吉洛尔衍生物相当的抗血管生成活性。
