2-(tert-Butoxycarbonylamino)-2-(2-fluorophenyl)acetic acid
The title compound, C(13)H(16)FNO(4), consists of conventional, centrosymmetric carboxyl-ate dimers. These dimers form infinite polymeric chains due to inter-molecular N-H⋯O hydrogen bonding. The 2-fluoro-phenyl unit is disordered over two sets of sites with an ocupancy ratio of 0.915 (3):0.085 (3).

The title compound, C(17)H(18)N(2)O(3), is approximately planar, owing in part to an intra-molecular bifurcated O-H⋯(N,O) hydrogen bond; the dihedral angle between the two aromatic rings is 23.86 (9)°. In the crystal struture, centrosymmetrically related mol-ecules associate into dimers via the eight-membered carboxyl-ate {⋯H-O-C=O}(2) synthon.

In the mol-ecule of the title compound, C(29)H(40)O(6), the carbon atom belonging to the propyl chain is connected to two aromatic rings that open up the C(ar-yl)-C-C(ar-yl) angle to 111.5 (1)°. The four-atom -O-CH(2)-C(=O)-O- linkage between the aromatic ring and the tert-butyl group assumes a (-)anti-periplanar conformation for one substituent and a (-)syn-periplanar conformation for the othe...

The title compound, C(15)H(20)O(3), is bent with a dihedral angle of 67.28 (9)° between the mean planes of the phenyl ring and a group encompassing the ester functionality (O=C-O-C). In the crystal, mol-ecules related by inversion symmetry are connected by weak C-H⋯O inter-actions into infinite chains. On one side of the mol-ecule there are two adjacent inter-actions between neighbouring mol-ec...
