Neuromuscular blocking agents of formula
wherein X is an anion are useful as skeletal muscle relaxants during surgery. They are prepared by esterification of an N-hydroxypropyl isoquinoline reactant with an octendioic acid. The resulting compounds, which preferably have E-configuration at the olefinic double bond can be separated into diastereoisomers. Novel N-hydroxypropyl isoquinoline intermediates are prepared by reacting the corresponding N-methyl isoquinoline with X.(CH3)3OH where X corresponds to anion X-.
式中 X 为阴离子的神经肌肉阻断剂可在手术过程中用作骨骼肌松弛剂。 它们是通过 N-羟丙基
异喹啉反应物与
辛二酸的酯化反应制备的。 所生成的化合物最好在烯烃双键上具有 E 构型,可以分离成非对映异构体。 新型 N-羟丙基
异喹啉中间体是通过相应的 N-甲基
异喹啉与 X.(
CH3)3OH 反应制备的,其中 X 相当于阴离子 X-。
