"Customizable" units in Di- and tripeptides: Selective conversion into substituted dehydroamino acids
The selective conversion of serine or threonine units of di- and tripeptides into substituted dehydroamino acids is reported. Thus, these common α-amino acids undergo a scission-phosphorylation process to give α-amino phosphonate residues. A Horner-Wadsworth-Emmons reaction with aldehydes or ketones follows to afford the final products with excellent Z-stereoselectivity (Z:E > 98:2). In this way, a single peptide precursor can selectively be transformed into a variety of derivatives.
