N-(Fluoren-9-ylmethoxycarbonyl)-l-isoleucine
In the crystal structure of the title compound [systematic name fluoren-9-ylmethyl N-(1-carb-oxy-2-methyl-butyl)carbamate], C(21)H(23)NO(4), the mol-ecular plane of the O=C-NH-C(α) unit is slightly pyramidalized. The N atom deviates from the basal plane by 0.2086 (12) Å. The O=C-N-C(α) torsion angle is -17.2 (2)°, and the C-N and O=C bond lengths are 1.3675 (17) and 1.2122 (17) Å, respectively....

THE TITLE COMPOUND [SYSTEMATIC NAME: fluoren-9-yl N-(1-carb-oxy-3-methyl-butyl)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 inter-molecular hydrogen bonds (O-H⋯O and N-H⋯O)...

In the title compound, C(20)H(15)N, the fluorene unit is essentially planar [r.m.s. deviation 0.0334 Å] and the benzene ring bound to the imine N atom bears a methyl group which is nearly coplanar [dihedral angle 0.5 (1)°]. The dihedral angle between the substituent benzene ring and the 9H-fluoren-9-imine unit is 71.1 (3)°. Inter-molecular π-π inter-actions between the benzene rings of adjacent...
متن کاملN-(Fluoren-9-ylmethoxycarbonyl)-l-aspartic acid 4-tert-butyl ester
The bond distances and bond angles of the title compound, C(23)H(25)NO(6), are consistent with values typically found for fluoren-9-ylmethoxy-carbonyl-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 inter-molecular hydrogen bonds, forming a two-dimensional sheet structure paralle...
متن کاملN-[(9H-Fluoren-9-ylidene)(2-methoxyphenyl)methyl]-1,1,1-trimethylsilanamine
The title mol-ecule, C24H25NOSi, is a hydrolysis product of the reaction between 9-tri-methyl-silyfluorenyl lithium and 2-meth-oxy-benzo-nitrile. The fluorene ring system is substanti-ally planar, with an r.m.s. deviation of 0.0288 Å from the best-fit plane through its 13 C atoms. This plane forms a dihedral angle of 58.07 (7)° with the 2-meth-oxy-benzyl-amine ring plane. In the crystal, mol-ec...
