Abstract
The selective thionation of α acetylamino β [4(1,2 dihydro 2 oxoquinoline)]propionic acid and its ester with phosphorus pentasulfide as a thionation reagent yielded the target compound α acetylamino β [4(1,2 dihydro 2 thioquinoline)]propionate. The structure of the new compound was studied by IR、UV、\+ 13 C NMR、GC/MS and Element analysis,and substitutional site of thionation of acetylamine was discussed.
