N-Benzyloxycarbonylendothiodipeptide esters, 3, are synthesized without racemization from the corresponding N-benzyloxycarbonyldipeptide esters, 2, using 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide, 1, as thionation reagent. The benzyloxycarbonyl amino-protecting group (Z) is removed from 3 by using HBr-AcOH.
的N- Benzyloxycarbonylendothiodipeptide酯,3,在没有外消旋作用合成从相应的N- benzyloxycarbonyldipeptide酯,2,使用2,4-双(4-甲氧基苯基)-1,3,2,4-二硫杂-2,4-二硫化物,1,作为硫磺化试剂。通过使用HBr-AcOH将苄氧基羰基氨基保护基(Z)从3中除去。
