, p. 274 - 283 (2007/10/03)
The synthesis and characterization of four new macrocyclic host compounds 1-4 having modified diphenylmethane units as bridging elements and two endo-orientated carboxylic acid groups attached to aromatic building blocks are described. The complexation pr
Oxidation of Aromatic Compounds. II. Oxidation of Methyl Derivatives of Benzoic Acid and Acetophenone in the System HSO3F-PbO2

Low-temperature oxidation of methyl derivatives of benzoic acid and acetophenone in the system HSO3F-PbO2 proceeds with intermediate formation of radical cations and results in replacement of hydrogen atom in methyl group or benzene ring.The reaction allows preparation of various substituted derivatives of benzyl alcohols and alkylated phthalides.
Tetrahydrofuran-containing macrocyclic polyether carboxylic acids
-
, (2008/06/13)
A series of tetrahydrofuran-containing, macrocyclic polyether compounds. The macrocycles have a 21-membered ring, incorporating six oxygen atoms, and they have a carboxy group (or a salt thereof) directed towards the interior of the ring. Administration of the compounds of the invention to ruminant animals (e.g. cattle and sheep) modifies their digestive fermentation processes such that the volatile fatty acids produced in the rumen contain a higher proportion of propionates rather than acetates, thereby increasing the efficiency of feed utilization in said ruminant animals. Additionally, the compounds of the invention show antibacterial activity in vitro against certain gram-positive microorganisms.
