4,4′-[p-Phenylenebis(oxy)]dibutanoic acid
The complete mol-ecule of the title compound, C(14)H(18)O(6), has a center of inversion at the centroid of the benzene ring and the asymmetric unit contains one half-mol-ecule. The conformation of the side chain is anti [C-C-C-C = -171.40 (17)°]. In the crystal, pairs of head-to-head carb-oxy-lic acid O-H⋯O hydrogen bonds link the mol-ecules into infinite zigzag chains propagating along [130]. ...
متن کاملProduct Formation from Ferrous Oxy-Cytochrome P-450
Since the state of biological hydroxylation was perceptively summarized in fact and projection by Boyd (1972), extraordinary progress has been made both in the isolation of a variety of the mammalian enzymes from liver and adrenal tissues (Takemori et al., 1975; Imai & Sato, 1974; Van der Hoeven et al., 1974) and in the establishment of the nature of oxygen intermediates and the role and site o...
متن کامل{2,6-Bis[(diphenylphosphanyl)oxy]phenyl-κ3 P,C 1,P′}iodidonickel(II)
In the title complex, [Ni(C(30)H(23)O(2)P(2))I], the divalent Ni atom is coordinated by two P atoms and one C atom from the 1,3-bis-[(diphenyl-phosphan-yl)-oxy]benzene ligand; the distorted square-planar geometry is completed by an iodide ligand. The largest distortions from ideal square-planar geometry are reflected in the P-Ni-P angle of 164.20 (2)° and the P-Ni-C angles of 82.09 (6) and 82.1...
متن کاملMethyl ({[(4E)-1,3-dimethyl-2,6-diphenylpiperidin-4-ylidene]amino}oxy)acetate
In the title compound, C22H26N2O3, the piperidine ring exhibits a chair conformation. The phenyl rings attached to the piperidine at the 2- and 6-positions have axial orientations. These rings make a dihedral angle of 49.75 (11)°. The amino-oxy acetate group attached at the 4-position has an equatorial orientation. In the crystal, inversion dimers linked by pairs of C-H⋯π inter-actions occur.
متن کاملHighly regio- and enantioselective multiple oxy- and amino-functionalizations of alkenes by modular cascade biocatalysis
New types of asymmetric functionalizations of alkenes are highly desirable for chemical synthesis. Here, we develop three novel types of regio- and enantioselective multiple oxy- and amino-functionalizations of terminal alkenes via cascade biocatalysis to produce chiral α-hydroxy acids, 1,2-amino alcohols and α-amino acids, respectively. Basic enzyme modules 1-4 are developed to convert alkenes...
