A NEW SYNTHETIC STRATEGY FOR HETEROANTHRACYCLINES: TOTAL SYNTHESIS OF D-RING THIOPHENE ANALOGS OF DAUNOMYCIN

The strong base-induced cycloaddition of appropriately functionalized thiophene analogs of homophthalic anhydride constitutes a highly regiospecific and convenient route to the D-ring thiophene analogs (2 and 3) of daunomycin.
