Phthaloyl-glycine tert.butyl ester

Phthaloyl-glycine tert.butyl ester is a glycine-based amino acid derivative in which the amino group is acylated with a phthaloyl (phthalimide-like) protecting group and the carboxyl group is esterified as a tert-butyl ester. The molecule therefore bears a protected α-amino functionality, a tert-butyl ester carbonyl, and the phthaloyl aromatic imide/amide carbonyl system, with the side chain remaining as the glycine methylene unit. In peptide and amino acid chemistry workflows, this protected ester format functions as a stable intermediate that can be handled for stepwise assembly or further derivatization, while the phthaloyl group and tert-butyl ester provide chemoselective control over subsequent deprotection and coupling steps.
