Description

(S)-1-tert-Butyl 2-methyl piperazine-1,2-dicarboxylate hydrochloride features a chiral piperazine core with orthogonal ester and methyl functionalities, enabling selective derivatization in asymmetric synthesis. The hydrochloride salt enhances solubility and stability under standard bench conditions, facilitating direct use in peptide coupling and medicinal chemistry workflows.

Application

(S)-1-tert-Butyl 2-methyl piperazine-1,2-dicarboxylate hydrochloride serves as a stereochemically defined chiral building block for medicinal chemistry campaigns. The protected piperazine core enables selective functionalization at nitrogen centers, with the tert-butyl and methyl groups offering orthogonal reactivity and enhanced stability during downstream transformations. Its crystalline form facilitates handling and purification, while the hydrochloride salt improves solubility in common organic solvents—ideal for modular synthesis of bioactive heterocycles and pharmaceutical intermediates.
