Highly Efficient Coupling of β-Substituted Aminoethane Sulfonyl Azides with Thio Acids, toward a New Chemical Ligation Reaction
摘要:
A highly efficient coupling of protected beta-substituted aminoethane sulfonyl azides with thio acids is reported. In the case of peptide thio acids, this method encompasses a new chemoselective ligation method. Furthermore, the resulting a-amino acyl sulfonamides can be alkylated with suitable electrophiles to obtain densely functionalized sulfonamide scaffolds.

A very efficient method for the synthesis of β-aminoethanesulfonyl azides is descibed. These aliphatic sulfonyl azides are accessible starting from a variety of protected amino acids, including those having functionalized side chains. Furthermore, these sulfonyl azides can be coupled to thio acids, and can be substituted with different aliphatic amines.
