| dc.description.abstract | The epoxidation of cinnatnylideneacetophenones have been already performed with hydrogen peroxide as oxidant in Julia's method [1] and with dimethyldioxirane [2], however no studies were performed using salen Mn(lll) complexes as catalysts. On these basis, we developed a study on the epoxidation of cinnamylideneacetophenones 1, catalyzed by coinmercially available Jacobsen's catalyst [salen Mn(IIl)] and using iodosy I benzene and hydrogen peroxide as oxidants. The structure of the epoxidation products 2-5, their stereochemistry and the regiochemistry of the monoepoxides 2 fotmation were established by ID and 2D NMR spectroscopy. These studies will be presented and discussed. | |
