Preparation and use of cysteine orthoesters for solid-supported synthesis of peptides

Huang, Zedu,Derksen, Darren J.,Vederas, John C.

supporting information; experimental part, p. 2282 - 2285 (2010/08/04)

Synthesis of a chiral cysteine derivative 2 with the carboxyl protected by an acid-labile 4-methyl-2,6,7-trioxabicyclo[2.2.2]octyl (OBO) orthoester is reported. A disulfide anchoring strategy is used to link the sulfur of this OBO cysteine derivative onto
