neurokinin-1 (NK-1) receptor, is described. The synthetic procedure starts from p-fluorobenzaldehyde to access the racemic morpholinone 2 via a modified Strecker synthesis and utilizes a diastereomeric salt resolution technique to accomplish the synthesis of 1 in enantiomerically pure form and good yield.
对映体纯的5-[[2- [1- [3,5-双(三氟甲基)苯基]乙氧基-3-(4-氟苯基)吗啉-4-基]甲基] -1,2-的简单收敛方法描述了二氢-1,2,4-三唑-3-酮1,一种有效的人类神经激肽-1(NK-1)受体的口服活性拮抗剂。合成过程从对氟苯甲醛开始,通过改进的Strecker合成方法获得外消旋吗啉酮2,并利用非对映异构体盐拆分技术完成对映体纯形式和高收率的1的合成。
