Four isomeric bicyclic sugar amino acids (SAAs) were prepared from an α-acetylenic-C-glucoside by employing a Petasis olefination and a ring-closing metathesis (RCM) as key steps. The applicability of the resulting SAAs in solid-phase peptide synthesis was demonstrated by the synthesis of a tetrapeptide.
通过采用 Petasis 烯化和闭环复分解 (RCM) 作为关键步骤,从 α-炔-C-
