| Summary: | 碩士 === 國立交通大學 === 應用化學系 === 83 === Reaction of cis-r-oxo-a,b-unsaturated thioesters with
sodiumdride, Grignard reagents, and allylsilanes at low
temperature gave the r-substituted-a,b-butenolides. On the
other hand, Reaction of the trans-r-oxo-a,b-unsaturated
thioesters with sodium borohydride, Grignard reagents, and
allylsilanes at low temperature gave the a,b-unsaturated
thioesters. Reaction of the cis-r-oxo-a,b-unsaturated
thioesters with silica gel gave the r-alkylidene-a,b-
butenolides.
