A New Synthetic Approach towards Adriamycin

An improved route to 3,4-dihydro-2-phenylnaphthofuran-5-one (2) and a convenient preparation of furan-3,4-dicarbaldehyde (4) are described.The dihydro-derivative of (2) was condensed with (4) to give 4-(4-formyl-3-furylmethyl)-2-phenylnaphthofuran-5-one (5), which after preparation of its 1,3-dithiolan derivative was photocyclized to a polycyclic compound (7).Owing to problems of deprotection of (7) further steps towards adriamycin (1) were abandoned.
