Salvianolicacid F (la) and przewalskinic acid A (2a) are phenolic acids isolated from the traditional and herbal Chinese medicines Salvia miltiorrhiza (1) and S. przewalskii (2). The chemical structures of these nvo compounds represent the main carbon skeletons of the biologically active depsides salvianolicacid A and B isolated from S.miltiorrhiza (3.4). 丁he present paper reports the synthesis of the methyl ether protected phenolic acids, tetnimetfayl salvianolic acid F (lb) and trimethyl przewaiskinic acid A (2b).
