The protected hydroxyethylene dipeptide isostere of Phe-Arg and the tripeptide derivative 1 were synthesized as components of potential peptidase inhibitors. Key to the success of these syntheses is selective rhodium-catalyzed hydroboration in the presence of a readily reduced lactone. A convenient one-pot conversion of azides to diprotected guanidines was developed on the basis of the Staudinger reaction
合成了被保护的Phe-Arg的羟乙烯二肽等排体和三肽衍生物1作为潜在的肽酶抑制剂的成分。这些合成成功的关键是在容易还原的内酯存在下的选择性铑催化的硼氢化反应。在施陶丁格反应的基础上,将叠氮化物方便地一锅转化为双保护的胍。
