of the reaction of homophthalic anhydride and N-(1-methyl-1H-pyrrol-2-yl-methylidene)-phenethylamine was studied. Mixtures of the expected trans- and cis-1,2,3,4-tetrahydroiso-quinoline-4-carboxylic acids trans-4 and cis-4 were obtained along with by-products 5 and 6. The ratios of all products and the diastereomers, obtained under different reaction conditions, were established by pmr. THF as a solvent
研究了高邻苯二甲酸酐与N-(1-甲基-1 H-吡咯-2-基-亚甲基)-苯乙胺反应的立体化学过程。的混合物所预期的反式-和顺-1,2,3,4-四氢异喹啉-4-羧酸反式- 4和顺式- 4用沿副产物得到的5和6。通过pmr确定在不同反应条件下获得的所有产物和非对映异构体的比例。在这种类型的反应中,首次将THF作为溶剂和超声处理。使反应对任何异构体非对映选择性。反式4的羧基将其在四个步骤中转变成各种环状氨基甲基,得到许多新的并入了给定药理学意义的片段的四氢异喹啉酮反式10a-i。研究了减少10a-i。
