Abstract

Despite the inherent instability of C2-substituted cis-cyclobutane β-aminoacids, incorporation of such residues into peptides is shown to be possible through use of a 1- amino-2-(hydroxymethyl) cyclobutane derivative as a stable β-aminoacid surrogate. This synthetic strategy was validated by the synthesis of a rhodopeptin analogue.
