conversion of a cinnamic acid derivative to the corresponding phenylalaninederivative could be achieved. The phenylalaninederivative was subsequently telescoped to a Pictet–Spengler reaction with formaldehyde, and the corresponding tetrahydroisoquinoline derivative was isolated in 60–70% yield with >99.9:0.1 er. On the basis of our screenings, carbonate/carbamate-buffered ammonia at an NH3 concentration
开发了一种使用工程化的苯丙氨酸氨裂合酶(PAL)酶的方法,作为通往olodanrigan(EMA401)关键中间体的替代途径的一部分。在本报告的第一部分中,介绍了筛选最佳反应条件的详细结果,然后讨论了所研究的几种后处理策略。在PAL催化的反应中,肉桂酸衍生物向相应的苯丙氨酸衍生物的转化率可达到70-80%。随后将苯丙氨酸衍生物与甲醛进行伸缩反应,以进行Pictet-Spengler反应,并分离出相应的四氢异喹啉衍生物,收率60-70%,> 99.9:0.1 er。根据我们的筛选,碳酸盐/氨基甲酸酯缓冲的氨为NH 3发现最佳浓度为9-10 M,pH值为9.5-10.5。可以实现低至2.5 wt%的酶负载(E:S = 1:40 w / w),并且发现3–9 v / w(1.17–0.39 M)之间的底物浓度与反应条件兼容。在最后的过程中应用了温度梯度:在利用熵项的温度依赖性并随后冷却至20°C
