O-tert.Butyl-trans-4-hydroxy-L-prolinetert.butyl ester hydrochloride is a protected, esterified proline derivative in which the trans-4-hydroxy substituent is present on the pyrrolidine ring and the amino acid backbone is converted to a tert-butyl ester. The molecule bears a tert-butyl ether (O-tert-butyl) protecting group on the 4-hydroxyl side chain and a tert-butyl ester with the amino functionality present as a hydrochloride salt, while the L stereochemical designation is specified for the proline center. This compound is used as a building block for stepwise peptide synthesis and related proline-containing derivative preparation, where the protecting groups support chemoselective handling of the hydroxyl and carboxyl functionalities during coupling and subsequent transformations.
