碩士 === 國立交通大學 === 應用化學系分子科學碩博士班 === 100 === In this study, we used phosphines, unsymmetric diynes and aldehydes to obtain the gamma-lactone intermediates bearing ylide functionality. We characterized these products by 1H, 13C, 31P, IR, Mass and X-ray diffraction analyses. These readily available structures may be adventageous to the total synthesis of molecules having lactone moiety. In addition, in the same one-pot reaction of phosphines, unsymmetric diynes and aldehydes, we found another unknown products. After characterized by 1H, 13C, IR, Mass and X-ray diffraction analyses, we determined the structure of the unknown product with a furan structure. By changing the condition of reactions to investigate the two product selectivity, and discuss the reaction mechanism.
