Hydroxyethylene dipeptide isosteres L-685,434, L-682,679 and L-685,458 were synthesized in a few steps by a sequence involving an allyltrichlorostannane coupling with an α-aminoaldehyde followed by hydroboration of the corresponding 1,2-syn and 1,2-anti aminoalcohols to give the diols, lactonization under TPAP conditions, lactone opening and peptide coupling with the desired amine or dipeptide amide.
羟乙基二肽等效体L-685,434、L-682,679和L-685,458通过一系列步骤合成,包括与烯丙基三氯锡烷的偶联反应生成α-氨基醛,随后对相应的1,2-顺式和1,2-反式氨基醇进行硼氢化反应生成二醇,在TPAP条件下内酯化,内酯开环并与所需胺或二肽酰胺进行肽偶联反应。
