Anwendungen

1,1-Dioxobenzo[b]thiophen-2-ylmethyl chloroformate is used for protection of amino acids as their benzothiophenesulfone-2-methoxycarbonyl (Bsmoc) derivatives, which represent a significant improvement in solid-phase peptide synthesis over the corresponding Fmoc derivatives.

Bemerkungen

Store under inert gas. It is sensitive to moisture. Store in a cool, dry conditions in well sealed containers. Incompatible with oxidizing agents and bases.

Reagent introduced by Carpino for protection of amino acids as their benzothiophenesulfone-2-methoxycarbonyl (Bsmoc) derivatives, which represent a significant improvement in solid-phase peptide synthesis over the corresponding Fmoc derivatives. They are more readily cleaved by base, particularly tris(2-aminoethyl)amine: J. Am. Chem. Soc., 119, 9915 (1997); J. Org. Chem., 64, 4324 (1999).
