Three new lignans, ficusal (1) and ficusesquilignans A (2), B (3) and one new gamma-lactone, ficusolide diacetate (4), were isolated from the wood of Ficus microcarpa L.f. Their structures were determined by spectral evidence.

Phenyliodine(III) diacetate-induced oxidation of 2-(2-hydroxynaphthyl)benzoxazoles in alcohols, regioselectively afforded dearomatized products: 1-(benzoxazol-2-yl)-1-alkoxynaphthalen-2(1H)-ones and 1-(benzoxazol-2-yl)naphthalene-2,3-diones. Further, these products were also synthesized one-pot either from (E)-1-(((2-hydroxyphenyl) imino)methyl)naphthalen-2-ol or 2-aminophenol 2-hydroxynaphthal...

Hydrochloric acid and/or sodium hydroxide may be used during manufacture to adjust pH of suspension to approximately 6. Triamcinolone diacetate is practically insoluble in water; soluble in chloroform; sparingly soluble in alcohol and in methanol; and slightly soluble in ether. This preparation is suitable for parenteral administration through a 23-gauge needle (or larger), but NOT suitable for...

A modified Gompertz equation was used to model the effects of temperature (55, 60, and 65 degrees C), sodium lactate (0, 2.4, and 4.8%), and sodium diacetate (0, 0.125, and 0.25%) on inactivation of Listeria monocytogenes strain MFS 102 (serotype 4b) in frankfurter slurry. The effects of these factors were determined on the shouldering region (parameter A), maximum death rate (parameter B), and...

The title compound, C(12)H(14)O(6), was prepared by the Williamson reaction of 1,4-dihydroxy-benzene and methyl chloro-acetate with phase-transfer catalysis. The compound lies on an inversion center. The structure is stabilized by weak C-H⋯π inter-actions.

In the title compound, C(14)H(18)O(6), a crystallographic center at the centroid of the aromatic ring generates the complete mol-ecule which is planar within 0.085 (1) Å for the non-H atoms. In the crystal, weak C-H⋯O and C-H⋯π inter-actions link the molecules.
