Reduction and alkylation with benzyl iodide gave 4-(benzyloxy)naphthol. Sulfation and chlorosulfuric acid in N,N-dimethylaniline gave potassium 1-(benzyloxy)-4-naphthol sulfate. Catalytic hydrogenation, alkylation with [[[(trifluoromethyl)sulfonyl]oxy]methyl]oxirane, and amination in isopropylamine gave 8. Racemic 8 was found to be 100-1000 times less potent than racemic propranolol as a beta-adrenergic
4'-羟基普萘洛尔硫酸盐最近被确定为普萘洛尔的主要代谢产物(Inderal)。为了确定结构并进一步研究其分布和生物学活性,我们使用1,4-萘醌作为起始原料合成了8种化合物。用苄基碘还原和烷基化得到4-(苄氧基)萘酚。在N,N-二甲基苯胺中硫酸化和氯硫酸得到1-(苄氧基)-4-萘酚钾硫酸盐。催化氢化,用[[[((三氟甲基)磺酰基]氧基]甲基]环氧乙烷烷基化,并在异丙胺中胺化,得到8。外消旋8的效能比外消旋普萘洛尔作为β-肾上腺素受体阻断剂的效力低100-1000倍。那只狗。
