چکیده
In the title compound, C(14)H(27)NO(5), the hydr-oxy group and one of the acetate carbonyl O atoms are linked by an intra-molecular O-H⋯O hydrogen bond, forming an eight-membered ring. This inter-action gives rise to an asymmetric mol-ecular conformation.

The complete molecule of the title compound, C(24)H(30)O(6), is generated by a crystallographic inversion centre. In the unique part of the mol-ecule, the four-atom -O-CH(2)-C(= O)-O- chain between the benzene ring and the tert-butyl group assumes a zigzag conformation [O-C-C-O torsion angle = -162.3 (1)°].

The preparation of triazamacrocyclic hydroxypyridinonate (HOPO-TACN) derivatives as potential chelators for metals in biomedical applications was reported. The synthesis is based on a convergent synthetic approach, in which the key intermediate di-tert-butyl-2,2'-(1,4,7-triazonane-1,4-diyl) diacetate was coupled with a hydroxypyridinonate pendant arm. The method is suitable for rapid syntheses ...
متن کاملDi-tert-butyl 2,2′-(biphenyl-2,2′-diyldioxy)diacetate
The title compound, C(24)H(30)O(6), does not exhibit π-π inter-actions due to the steric effect of the bulky tert-butyl groups present in the mol-ecule. The presence of these groups at the 2 and 2' positions hinders the free motion of the benzene rings relative to each other, causing them to adopt an anti-periplanar arrangement. The benzene rings are twisted by just under 50.96 (17)° with respe...

In the title mol-ecule, C(37)H(38)O(6), the non-fused C atom belonging to the five-membered ring of the fluorene system is connected to two p-phenyl-ene rings, the rings opening up the C(ar-yl)-C-C(ar-yl) angle to 113.1 (1)°. The four-atom -O-CH(2)-C(=O)-O- chain between the p-phenyl-ene ring and the tert-butyl group assumes a more regular W-shaped conformation for one substituent [O-C-C-C tors...

In the title compound, C(33)H(36)O(6), two naphthalene ring systems are connected through a methyl-ene linkage [C-C-C = 114.9 (2)°]; the ring systems are aligned at an angle of 76.5 (1)°. Of the two -O-CH(2)-C(=O)-C(CH(3))(3) substituents, one adopts an extended conformation whereas the other is U-shaped. In the crystal, mol-ecules are linked via weak C-H⋯O hydrogen bonding, forming supra-molec...
