In the present work a novel improved and convenient procedure for the synthesis of oxazoles has been developed. Acetamide, instead of ammonium acetate, was used to react with phenacyl benzoates in boiling xylene in the presence of as the catalyst. According to this new synthetic route, nine oxazole compounds were readily prepared as single products in reasonably high yields. On the basis of the experimental

Abstract A new route to tetrahydrofurofurane lignans 8 is present, which starts with substituted benzoate following a 7 stepsyntheses, and is distinctly shorter, more economic and efficient than any of the previous approaches to the target reported in the literature. The keystep to establish the first furane ring 2 benefits the remarkable ease of the Diels-Alder reaction of 2,4-diaryloxazole 1 with
