Boc-D-Serinol(Bzl) is a selectively protected derivative of D-serinol, serving as a key building block in peptide synthesis and organic chemistry. The tert-butoxycarbonyl (Boc) group protects the amino functionality, while the benzyl (Bzl) group protects one of the primary hydroxyl groups, leaving the other primary hydroxyl available for selective activation and coupling reactions. This enables the precise incorporation of serinol units into peptide chains, enhancing control over structure and reactivity in the synthesis of complex peptides, peptidomimetics, and bioactive molecules. It is widely applied in pharmaceutical development for creating stable peptide-based drugs and in medicinal chemistry for preparing intermediates in drug discovery.
