N-(Methoxycarbonyl)-D-tert-leucine is a protected amino acid derivative in which the amino group of D-tert-leucine is blocked with a methoxycarbonyl (–COOCH₃) protecting group. It is commonly used as a building block in peptide synthesis and pharmaceutical chemistry to prevent undesired reactions at the amino group while allowing selective coupling at the carboxyl group.
