reaction takes a short time and is non-catalyzed and reproducible on a gram scale. The environmentally benign methodology provides a novel alternative, to the conventional methodologies, for the synthesis of mono- and disubstituted Mannich bases of 4-hydroxyacetophenone. All compounds were well-characterized by FT-IR, 1H NMR, 13C NMR, and mass spectrometry. The structures of 1-4-hydroxy-3-[(morpholin
[Object]: To provide a compound having a novel structure effective against
Hemophilus influenzae
and erythromycin resistant bacteria (for example, resistant pneumococci and streptococci) as well as against conventional erythromycin sensitive bacteria.
[Solution]: A novel 10a-azalide compound represented by the formula (I), a pharmaceutically acceptable salt thereof or a solvate thereof, or an intermediate for the preparation of the same. The compound of the present invention has superior antibacterial activity against
Hemophilus influenzae
, erythromycin resistant pneumococci and the like, and therefore, the compound can be used as a therapeutic agent of infectious diseases.
