In the title mol-ecule, C(29)H(26)N(2)O(2), there are two strong intra-molecular O-H⋯N hydrogen bonds involving the hydr-oxy and imine groups, forming S(6) ring motifs. The dihedral angles between adjacent phenyl rings and phenol-containing planes are 85.27 (19) and 91.38 (18)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds connect mol-ecules into a two-dimensional network.
As a result of many requests for a phosphatase method which would use the phenyl phosphate substrate of King and Armstrong (1934), but which would substitute a determination of the liberated inorganic phosphate for that of phenol, we have developed two procedures which are described in this paper. The principal reason for a method in which the final measurement is of inorganic phosphate is that...
For the determination of the phosphatase content of yeast many methods have been used (l-3). The usual method is to hydrolyze a glycerophosphate and measure the amount of inorganic phosphate liberated. King and Armstrong (4) have shown, however, that phenyl phosphate could be used as a substrate and the phenol det,ermined. To be satisfactory the method chosen must give a measurable amount of hy...
Reactions of benzoyl pyridine, o-phenylenediamine and anhydrous ZnX2 in methanol afford imine complexes [Zn(L1)X2] (X = Cl, 1; X = Br, 2) in good yields (L1 = (E)-N(1)-(phenyl(pyridin-2-yl)methylene)benzene-1,2-diamine). The reduction of 1 with NaBH4 affords (E)-N(1)-(phenyl(pyridine-2-yl)methylene)benzene-1,2-diamine (L2H). The reaction of L2H with [Ru(II)(PPh3)3Cl2] results in the oxidative d...
This study presents antibacterial activity of several organic metabolites produced by a fish pathogen, Acinetobacter sp. strain An 2, from marine ecosystem of Goa. Cell extract demonstrated stronger inhibitory effects on Gram negative bacteria as compared to common antibiotics. GC-MS analysis of crude cell extract revealed presence of potential antimicrobials (butylated hydroxytoluene, phenol, ...
In the title compound, C(21)H(17)N(3)O(3), the dihydro-quinazoline ring adopts a screw-boat conformation and its stereogenic C atom has an S configuration. The dihedral angle between the mean planes of the two hy-droxy-phenyl rings is 86.61 (12)°. The amino H atom forms an intra-molecular hydrogen bond with a phenol O atom, while the hydrazine N atom acts as an acceptor for the H atom of the ot...
