초록
Six novel 5-substituted-1-[2-(3-methoxy-2-hydroxyphenyl)-1-methoxyethyl]uracils 2a-f were prepared by condensation of 2,4-bis(trimethylsilyloxy)-5-substituted uracils with 2,7-dimethoxy-2,3-dihydrobenzofuran (9) in the presence of Lewis acid. The 2,3-dihydrobenzofuran derivative 9 was obtained by intramolecular acetalization of 2-acetoxy-3-methoxyphenyl acetaldehyde (8) which was synthesized by oxidative cleavage of 1-allyl-2-acetoxy-3-methoxybenzene (7) using osmium tetroxide followed by
