Description

General description

(N-Isocyanoimino)triphenylphosphorane (Pinc) is a bench-stable solid reagent widely used in organic synthesis. It is an amphoteric compound with unique properties that make it a versatile tool for various applications, including heterocycle synthesis and macrocyclization of peptides. Pinc facilitates cyclization and incorporation of a conformational control element into peptide macrocycles, leading to desired drug properties such as improved membrane permeability, lipophilicity, and aqueous solubility. Its ability to form oxadiazoles offers opportunities for the development of new transformations.

Application

As reported by the lab of Andrei Yudin, Pinc enables zwitterionic-controlled generation of peptide macrocyles from linear peptides and aldehydes. It enables the formation of disubstituted 1,3,4-oxadiazoles by intercepting the key mixed anhydride characteristic of the Ugi reaction. Furthermore, the resulting peptide macrocycles containing oxadiazole exhibit improved drug properties such as cell-permeability and a rigid conformation.

Features and Benefits

• Bench-stable solid: Pinc is a stable reagent that can be easily handled and stored.
• Facilitates cyclization and incorporation of conformational control element: Pinc enables the formation of peptide macrocycles with a desired conformation, leading to improved drug properties.
