The structure elucidation of lavendamycin (1a), a newantitumorantibiotic related to streptonigrin (2) is described. The NMR spectra of 1a and several model compounds 3,4 < and 5a-b are also discussed.

and decarboxylation procedure using natural flavins as a catalyst and atmospheric oxygen as an external oxidizing agent has been successfully developed and applied to the synthesis of streptonigrone from streptonigrin. This reaction was achieved not only with streptonigrin analogues but also with structurally diverse electron-rich picolinic acidderivatives. The hydroxylation and decarboxylation may
