were derived from l-pipecolic acid in 96% optical purity. The versatility of this methodology is demonstrated with the synthesis of the (2R,2'R) and (2S,2'S) enantiomers of p-bromo and p-methoxy derivatives in similar yields and enantiomeric purities. Comparative neurochemical assessments of these synthesized enantiomers at purported dopamine, norepinephrine, and serotonin uptake sites along with locomotor
我们报道了哌醋甲酯(1)的单个对映异构体的首次不对称合成。从d-哌醇酸中获得1的(2R,2'R)和(2S,2'R)对映体,光学纯度> 99%,而1的(2S,2'S)和(2R,2'S)对映体为衍生自l-哌酸,光学纯度为96%。通过以相似的产率和对映体纯度合成对溴和对甲氧基衍生物的(2R,2'R)和(2S,2'S)对映异构体,证明了该方法的多功能性。这些合成的对映异构体在据称的多巴胺,去甲肾上腺素和5-羟色胺摄取位点的比较神经化学评估以及在大鼠中的运动活性研究也得到了报道。
