4-Methoxybenzoyl-meso-octamethylcalix[2]pyrrolidino[2]pyrrole: an acyl chloride derivative of a partially reduced calix[4]pyrrole
In the title compound, C(36)H(50)N(4)O(2), the two pyrrolidine rings have envelope conformations. The conformation of the macrocycle is stabilized by N-H⋯N hydrogen bonds and a C-H⋯N inter-action. The benzoyl ring is inclined to an adjacent pyrrole ring by 6.76 (9)°, with a centroid-to-centroid distance of 3.6285 (10) Å. In the crystal, apart from a C-H⋯O and a C-H⋯π inter-action, mol-ecules ar...

In the title compound, C(35)H(47)ClN(4)O, the two pyrrolidine rings have envelope conformations. The conformation of the macrocycle is stabilized by N-H⋯N hydrogen bonds and a C-H⋯N inter-action. The benzoyl ring is inclined to the adjacent pyrrole ring by 11.66 (11)°, with a centroid-centroid distance of 3.7488 (13) Å. In the crystal, molecules are linked by N-H⋯O hydrogen bonds into helical c...

There are two independent molecules in the asymmetric unit of the title compound, C(25)H(24)F(2)N(6), in which the N=N bonds adopt a trans configuration with distances in the range 1.262 (2)-1.269 (3) Å. The dihedral angles between heterocycles are 86.7 (2) and 85.6 (2)° in the two molecules while the dihedral angles between the heterocylic rings and the adjacent benzene rings are 13.4 (2) and ...
متن کاملInvestigation of substrate activation by 4-chlorobenzoyl-coenzyme A dehalogenase.
4-Chlorobenzoyl-coenzyme A (4-CBA-CoA) dehalogenase catalyzes the hydrolysis of 4-CBA-CoA to 4-hydroxybenzoyl-coenzyme A (4-HBA-CoA), using the carboxylate side chain of aspartate 145 to displace the chloride from C(4) of the benzoyl ring. Previous UV-visible, Raman, and 13C NMR studies of enzyme-bound substrate analog or product ligand indicated that the environment of the enzyme active site i...
