Peptide Bond Formation via Nα-Protected Diacyldiselenides
Abstract
A simple, straightforward, for the peptide bond formation employing corresponding carboxylic acids and amines derived
from amino acids via Nα
-protected diacyldiselenide is delineated. The key step of the synthesis is the in situ generation of
Nα
-protected diacyldiselenide using NaBH2Se3 as selenating reagent, followed by trapping with an amino acid ester leading
to the peptide. The formation of Nα
-protected diacyldiselenide was confirmed through TLC and HRMS analysis using crude
sample. The reaction is clean and all the products were obtained in moderate to good yields, including for sterically hindered
amino acids. The protocol is free from racemisation, compatible with Fmoc, Cbz and Boc groups

The synthesis of Nα-protected amino hydroxamic acids from Nα-protected amino acids employing versatile chlorinating agent CPI-Cl
Racemization free synthesis of Nα-protected amino hydroxamic acids from Nα-protected amino acids employing the versatile chlorinating reagent CPI-Cl has been described in one-pot. The present protocol has shown compability towards urethane protecting groups like Boc, Cbz and Fmoc, and side chain protections of amino acids showed complete tolerance. © ARKAT USA, In
