Novel Method for the Synthesis of 3′,4′‐Dideoxygenated Pyranmycin and Kanamycin Compounds, and Studies of Their Antibacterial Activity Against Aminoglycoside‐Resistant Bacteria
摘要:
A novel protocol for converting a trans-diol to an alkene under mild conditions was developed. This method let to the synthesis of a 3',4'-dideoxykanamycin (dibekacin) analog and a 3',4'-dideoxypyranmycin that were found to be active against aminoglycoside-resistant bacteria.

Using allylicaziderearrangement, a convenient method has been developed for the synthesis of 2′,3′-dideoxyaminoglycosides that are, otherwise, difficult to be prepared. The antibacterial activity of these novel aminoglycosides also confirms the indispensable role of 2′-NH2 group for both neomycin and kanamycin classes of aminoglycosides. A novel structural motif containing the hexylaminocarbonyl

A novel broad-spectrumaminoglycosideantibiotic, pyrankacin, has been prepared. In addition to the synthetic innovation in dideoxygenation and regioselective Staudinger reduction, we have obtained prominent antibacterial activity against several clinically important pathogens in the course of this work.
The invention relates to novel paranmycin compounds that have activity against gram positive and gram negative bacteria, preferably bacteria that are resistant to other antibiotics. Paranmycins are of the general formula
