The present invention relates to novel platensimycin derivatives, their intermediates and preparing methods of the same. Platensimycin is known as an effective antibiotic material having a broad antimicrobial spectrum and its derivatives are also expected to be effective antibiotic candidates. The present invention also relates to a novel preparing method of platensimycin. The intermediates used for the production of platensimycin and its derivatives of the present invention are tricyclo ketone derivatives and tetracyclo derivatives. Tetracyclo derivatives are prepared from tricyclo ketone derivatives prepared by carbonyl ylide [3+2] cycloaddition of dia-zoketone derivative.
