The modified Pictet–Spengler reaction of phenylethylbenzene sulfonamide with a commercially available glyoxal to construct 1-benzoyl- and 1-acetyl-1,2,3,4-tetrahydroisoquinolines 9a–n has been reported. The reaction could be accomplished, regardless of the oxygenation pattern on the aromatic ring, leading to the N-sulfonyltetrahydroisoquinoline analogs which are versatile intermediates for the synthesis
据报道,苯乙苯磺酰胺与市售的乙二醛经改进的Pictet-Spengler反应,可构建1-苯甲酰基和1-乙酰基1,2,3,4-四氢异喹啉9a – n。无论芳环上的氧化方式如何,均可完成该反应,从而得到N-磺酰基四氢异喹啉类似物,其是用于合成1,2,3,4-四氢异喹啉的新的硫半脲酮类似物的通用中间体。生物活性测试表明,大多数硫代半脲类化合物对MOLT-3细胞系均具有细胞毒性,IC 50值小于20μg/ mL。值得注意的是,1-乙酰基四氢异喹啉9j的硫半脲类类似物是对HuCCA-1,HepG2和MOLT-3细胞最有效的细胞毒性化合物。这项研究为进一步发展提供了新颖的先导分子。
