Abstract

Abstract No extra side-chain protection is needed for Ser, Thr, Tyr and Cys (nor for Asp and Glu) in peptide syntheses that are mediated by TMS-CN, whereby silylesters and ethers are formed and are stable enough even during activation of carboxylic components. This allows Head-to-Tail elongation strategies and fragment condensations without recourse to additional side-chain protection except for amine and amide functionalities. Moreover, ...
