3-Aryl-4-hydroxytetrahydroisoquinolines have been prepared from deoxybenzoins. The nitrosation of the latter derivatives has been improved and the catalytic reduction of the obtained oximinoketones has been carried out with the help of ultrasounds. Heterocyclization to the isoquinoline moiety occurred on the unprotected 1,2-aminoalcohol to give stereoselectively the corresponding hydroxylated heterocycle
3-芳基-4-羟基四氢异喹啉已由脱氧苯偶姻制备。后一种衍生物的亚硝化得到了改善,并且所获得的肟基酮的催化还原已经借助超声波进行了。在未保护的1,2-氨基醇上发生杂环化成异喹啉部分,从而以良好的产率立体选择性地给出了相应的羟基化杂环。
