N-(Fluoren-9-ylmethoxy­carbon­yl)-l-leucine

The title compound [systematic name: fluoren-9-yl N-(1-carb­oxy-3-methyl­butyl)carbamate], C(21)H(23)NO(4), exhibits torsion angles that vary from the typical values found in other Fmoc-protected amino acids, viz. the orientations of the fluorene and carboxyl groups [C—O—C—C = 93.8 (2) and N—C—C=O =...

description The title compound [systematic name: fluoren-9-yl N-(1-carb­oxy-3-methyl­butyl)carbamate], C(21)H(23)NO(4), exhibits torsion angles that vary from the typical values found in other Fmoc-protected amino acids, viz. the orientations of the fluorene and carboxyl groups [C—O—C—C = 93.8 (2) and N—C—C=O = −23.6 (2)°]. The crystal structure exhibits two inter­molecular hydrogen bonds (O—H⋯O and N—H⋯O) that link the mol­ecules into two-dimensional sheets parallel to the ab plane.
