and 8-phenylisoquinolin-4-ol (17), flexible analogues of aporphine, were synthesized in good yields using palladium-catalyzed Suzuki cross-coupling reactions from 8-bromotetrahydroisoquinolin-4-one (6) as a common intermediate. We also describe the synthesis of this novel intermediate through an easy and efficient method, which involved intramolecular Friedel–Crafts cyclization.
新8-(HET)aryltetrahydroisoquinolines(10 - 14),8-aryltetrahydroisoquinolin -4-醇(15,16),和8-苯基异-4-醇(17),阿朴啡的柔性类似物,在使用钯良好的收率合成催化的8-溴四氢异喹啉-4-酮(6)作为常见中间体的铃木交叉偶联反应。我们还描述了通过一种简单有效的方法合成这种新型中间体的方法,该方法涉及分子内Friedel-Crafts环化。
