The reaction of homophthalic anhydride with 1H-indol-3-carbaldimines was used for the preparation of trans- and cis-2-alkyl-3-indolyl-1-oxotetrahydroisoquinolin-4-carboxylic acids 3a–d. The stereochemistry of the reaction was investigated by means of 1H NMR spectroscopy. The carboxylic group of trans-3a–d was transformed stereoselectively via 4-hydroxymethyltetrahydroisoquinolin-1-ones into 4-(pht
高邻苯二甲酸酐的用1个反应ħ吲哚-3- carbaldimines用于制备反式-和顺-2-烷基-3-吲哚基-1- oxotetrahydroisoquinolin -4-羧酸3a-d中。通过1 H NMR光谱研究反应的立体化学。的羧酸基团的反式-图3a-d是通过4- hydroxymethyltetrahydroisoquinolin -1-酮立体选择性地转化为4-(邻苯二甲酰) -衍生物反式- 6A,6B和4-(咪唑基甲基) -衍生物反式- 8B-d 。化合物反式- 6A,6B和图8b-d中为antiaromatase活性进行测试,和初步结果表明,phthalimidomethylisoquinolinone反式- 6b中在50μM浓度用40%降低芳香酶的活性。
