Syntheses of Anisomycin Derivatives
The structure of anisomycin has been determined by X-ray investigation4 and the absolute configuration was confirmed by chemical correlation.5 Anisomycin has attracted considerable synthetic interest, and several synthetic studies, derivative syntheses as well as total syntheses, have been reported.6 Especially, the synthesis of its analogues has revealed the structure-activity relationship of ...

متن کاملSyntheses and activities of some bactobolin derivatives.
Some derivatives of bactobolin were prepared from bactobolin by dehydration or substitution reactions through tris(dimethylamino)alkoxyphosphonium salt formation. A derivative with low toxicity, 6-deoxybactobolin, showed moderate activity against Gram-positive and Gram-negative bacteria including methicillin-resistant Staphylococcus aureus.
متن کاملSyntheses of soluble, pi-stacking tetracene derivatives.
[reaction: see text] The syntheses of a series of fluorine- and alkyl/alkoxy-functionalized tetracenes are reported. These functional groups are found to improve the solubility in common organic solvents and tune molecular arrangement in solids. The crystal packing, electrochemical behavior, and UV-vis absorbance spectroscopy of these materials are discussed.
متن کاملSyntheses of 15N-labeled pre-queuosine nucleobase derivatives
Pre-queuosine or queuine (preQ1) is a guanine derivative that is involved in the biosynthetic pathway of the hypermodified tRNA nucleoside queuosine (Que). The core structure of preQ1 is represented by 7-(aminomethyl)-7-deazaguanine (preQ1 base). Here, we report the synthesis of three preQ1 base derivatives with complementary (15)N-labeling patterns, utilizing [(15)N]-KCN, [(15)N]-phthalimide, ...
