摘要：
Function-oriented synthesis of a class of liponucleoside antibiotics was investigated through rational simplification guided by previous structure-activity relationship studies of caprazamycins and muraymycins to address the issue associated with their molecular complexity. A lactam-fused isoxazolidine scaffold was designed, and a diverse set of lactam-fused isoxazolidines derivatives were constructed by intramolecular 1,3-dipolar cycloaddition of alkenyl nitrones. Several analogues exhibited moderate activity against a range of Gram-positive drug-resistant bacterial pathogens.
