โฆ Synopsis
A brief and convergent synthesis of the aglycone of the gilvocarcins M and E (and formally V) involving, in the key step, a Pd-mediated inmmolecular biaryl coupling, is reported.

hearing oxygenated suhstituents at C-l, 10 and 12, and an alkyl (methyl, ethyl) or vinyl group at C-8 constitute the common aglycone of a number of C-aryl glycoside antibiotics including, in particular, the gilvocarcins (M, la; E. 2a; V, 3a).' ravidomycin,2 and ~thers.~ Several of these antibiotics exhibit significant antitumor activity. *3 for example, gilvocarcin V is a DNA-intercalating agent of unusual potency' whose activity is enhanced by low-energy visible light ir&iatio@*' the therapeutic
