| Synthesis of Two Allergenic Constituents of Propolis and Poplar Bud Excretion  | | | | Abstract
| The prenyl ester and the phenylethyl ester of caffeic acid, formed in the bud excretion of poplar species, were shown recently to be the major contact allergens in bee-glue. An unambiguous synthesis of these compounds, based on the reaction of caffeic acid with l-bromo-3-methyl-2-butene and with ß-bromoethylbenzene, respectively, is reported. The synthetic products confirm the previously described structures of the natural products and allow further testing of their allergenic properties. | | | |
