GA21564

Fmoc-Cys(StBu)-OH

Also known as (2R)-3-(tert-butyldisulfanyl)-2-(9H-fluoren-9-ylmethoxycarbonylamino)propanoic acid

Was converted into the corresponding N-Me-Cys derivative in excellent yield·Educt for obtaining the Cys 4-methyl-2,6,7-trioxabicyclo[2,2,2]octyl (OBO) orthoester· The OBO ester was attached to a thiol resin as disulfide for obtaining peptides containing a C-terminal cysteine
