Ko N-Cbz-L-Valine (Z-Val-OH) (CAS: 1149-26-4) he ahua tiaki N-Cbz o L-Valine.Ko te N-Cbz-L-Valine he valine e tiakina ana e Cbz ka whakamahia nuitia i roto i te waahi o te whakahiato raau taero.Ko te L-Valine he waikawa amino nui e whakamahia ana hei whakauru i roto i nga hanganga whakapaipai, nga rongoa, me nga hua kai kararehe.He mea nui ano te L-Valine mo te tipu me te whakakore i te haukini i roto i te tangata.
Z-Amino Acid, ka taea te whakamahi i roto i te peptide synthesis, ka taea hoki te whakamahi hei takawaenga whakahiato waro, takawaenga rongoa, reagent biochemical, reagent matū ranei.
Ka taea te whakamahi i te N-Cbz-L-Valine ki te hanga i nga API penei i a Imatinib, Valaciclovir.
Me tango te 1.17Kg (10mol) o L-Valine, 5L o te 2mol/L konutai wairewa wai me te 1.06Kg (10mol) o te konutai warowaiha ki roto i te hohenga tauhohenga 20L, timata te whakaoho, i muri i te rewa katoa o L-Valine, whakaitihia te pāmahana o te te otinga ki raro i te 0 ℃, ka maturuturu 1 kei roto 2.05Kg(12mol) o benzyl chloroformate, 4-dioxane otinga 5L, te pāmahana o te otinga i roto i te tukanga maturuturu ka pupuri i raro i te 20 ℃, i muri i te maturuturunga iho, ko te tauhohenga ko te 8h i te ruma pāmahana.I te mutunga o te tauhohenga, ka tangohia te wai tauhohenga ki te dichloromethane 2.5L, ka makahia te wahanga waro, ka whakamataohia te wahanga wai ki raro iho i te 10 ℃, ka whakahekehia te waikawa pūhaumāota ki te pH=2, ka whakaoho i te 10 ℃ mo te 30min , he nui te totoka ma ka whakahekehia, ka mahia te tātari, ka horoia te toenga tātari ki te wai, ka maka te totoka ma ki roto i te oumu whakamaroke korehau kia maroke, ka 93.7%.
