Tröger’s base analogues were prepared bearing methoxy groups in the 1,7-, 2,8-, 3,9- or 4,10-positions. These compounds were converted to their dihydroxy analogues in excellent yields upon treatment with boron tribromide and the 4,10-dihydroxy analogue could be prepared by directly from 4-hydroxyaniline. The synthetic utility of the dihydroxy-functionalised compounds as building blocks was demonstrated
制备了Tröger的碱基类似物,其在1,7-,2,8-,3,9-或4,10-位带有甲氧基。在用三溴化硼处理后,这些化合物以优异的产率转化为它们的二羟基类似物,并且可以直接由4-羟基苯胺制备4,10-二羟基类似物。通过合成二烷氧基和二酯Tröger的碱基类似物,证明了二羟基官能化化合物作为结构单元的合成效用。
