Preliminary studies on the synthesis of rancinamycins from nitrosugars
نویسندگان
چکیده
The structures (except stereochemistry) of the main components of the rancinamycin complex were determined with IR, UV, and NMR spectra. Rancinamycin I is a mixture of 5 isomeric components, designated Ia, Ib, Ic, Id and Ie. Rancinamycin II is also a mixture of 5 isomeric compounds, designated rancinamycins IIa-IIe. Differences in the acyl group or in stereochemistry probably account for the isomers. Rancinamycin III is a mixture of 4 isomeric components. The differences between the 4 isomers is unknown. Rancinamycin IV is 3,4dihydroxybenzaldehyde.

The production, isolation and characterization of rancinamycins I, II, III and IV have been described in a preceding communication." These metabolites, which exhibit in vitro activity against Gram-positive and Gram-negative bacteria, are produced by Streptomyces lincolnensis in media depleted of sulfur-containing inorganic or organic compounds. Rancinamycins I, II, III and IV behaved as single ...
متن کاملPreliminary Beneficiation and Washability Studies on Ghouzlou's Low-Ash Coal Sample
In the present research work, a low-ash coal, from Ghouzlou deposit in Iran, with an average ash content of 12% was subjected to some beneficiation experiments such as heavy media separation and flotation. Sieve analysis showed that 62.3% of the coal sample with the size of +2 mm had around 7.3% ash contents. Also, heavy media tests carried out on five size fractions revealed that by setting th...
