N-(Fluoren-9-ylmethoxycarbonyl)-L-aspartic acid 4-tert-butyl ester

K. Yamada, D. Hashizume and T. Shimizu

Abstract: The bond distances and bond angles of the title compound, C₂₃H₂₅NO₆, are consistent with values typically found for fluoren-9-ylmethoxycarbonyl-protected amino acids. The conformations of the backbone and the side chain are slightly different from those of L-aspartic acid. The crystal structure exhibits two intermolecular hydrogen bonds, forming a two-dimensional sheet structure parallel to the ab plane.
