A totalsynthesis of novel heptacyclic antibiotics cervinomycin A1 and A2 following a convergent approach is reported. The cornerstone of our strategy was the construction of the central ring D through photochemical electrocyclization. The oxazolo-isoquinolinone fragment (ABC rings) and the xanthone fragment (EFG rings) were assembled through relatively straightforward synthetic protocols and coupled
