An expedient synthesis of orthogonally protected lysinoalanine from Aloc-protected Garner's aldehyde

[摘要] An expedient synthesis of orthogonally protected lysinoalanine has been developed. We have prepared a novel Garner's aldehyde derivative bearing an Aloc group; reductive amination of this aldehyde with Fmoc-Lys-OPMB gave the lysinoalanine skeleton. This was then transformed into an orthogonally protected lysinoalanine derivative suitable for the synthesis of side-chain bridged cyclic peptides by solid phase peptide synthesis methods.
