摘要：
A number of the thieno[3,2-c][1,8]naphthyridin-4(5H)-ones are chemoselectively synthesized from 4-(4'-aryloxybut-2'-ynylthio)-l-phenyl-1,8-naphthyridin-2(1H)-ones in 82-90% yield by the formation of sulfoxide, followed by [2,3] and [3,3]sigmatropic rearrangement and an intramolecular Michael addition.
