Heterocyclic a-dehydroo -amino esters are obtained by the reaction of ethyl N-carbomethoxy oxamate with whalogened phosphorus ylids. In the preceding paper (l), we reported a novel synthesis of cr-dehydro Q -amino esters by condensation of phophorus ylids with t-butoxalyl iminoether. In this paper,
The Michael-addition of polyfluoroalkenoates with thiophenols in acetonitvile in the presence of Na- HC03 yielded the corresponding addition products, which were further treated with polyphosphoric acid (PPA) to give a series of new fluorine-containing thiochromones in good yields.
