dc.description.abstractOxidation of ortho-hydroxyphenyIketones with two molar equivalents of t h a l l i um ( I l l ) t r i o x o n i t r a t e (v) t r i h y d r a t e (TTN) in methanol (MeOH)/ trimethyl ortho-formate (TMOF) mixture ( l : l ) gives the corresponding 2-alkyl-2,3,3-trimethoxy-2,3-dihydrobenzofuran in high y i e l d . This r e a c t i o n c o n s t i t u t e s a simple and convenient method for the synthesis of benzofuran d e r i v a t i v e s. The ortho-hydroxyphenylketones are synthesised from the corresponding phenyl e s t e r s via Pries rearrangement. These benzofuran d e r i v a t i v e s are isomeric with lactones which are of value in cancer therapy.en_US
