Several novel approaches have been investigated for the synthesis of the LTD4/E4 antagonist LY290154. Significant improvements to the discovery route were first made by using an indoline nucleophile instead of an indolyl anion in the key substitution step. An alternative approach, introducing the 7-chloroquinoline moiety in the latest stages of the synthesis was then demonstrated. Interestingly, the
已经研究了几种新颖的方法来合成LTD 4 / E 4拮抗剂LY290154。首先通过在关键取代步骤中使用二氢吲哚亲核试剂代替吲哚基阴离子对发现路线进行了重大改进。然后证明了另一种方法,在合成的最新阶段引入了7-氯喹啉部分。有趣的是,后一种方法的关键中间体也是按照Katritzky方法在一锅法中获得的。最后,证明了一种不对称合成方法,该方法相对于McKillop报告的对映选择性路线具有明显优势。
