Chemoselective synthesis of thieno[3,2-c][1,8]naphthyridin-4(5H)-ones by tandem cyclization

A number of the thieno[3,2-c][1,8]-naphthyridin-4(5H)-ones are chemoselectively synthesized from 4-(4′-aryloxybut-2′-ynylthio)-1- phenyl-1,8-naphthyridin-2(1H)-ones in 82-90% yield by the formation of sulfoxide, followed by [2,3] and [3,3]sigmatropic rear

Regioselective synthesis of biologically interesting pentacyclic polyheterocycles by sequential thio-Claisen and AlCl3 catalyzed oxy-Claisen rearrangement of 4-(4′-aryloxybut-2′-ynylthio)-1-phenyl- 1,8-naphthyridin-2(1H)-one

A number of 4-aryloxymethyl-6-phenyl-2H-thiopyrano[3,2-c][1,8]naphthyridin- 5(6H)-ones were regio-selectively synthesized in 82%-95% yields by the thermal Claisen rearrangement of 4-(4′-aryloxybut-2′-ynylthio)-1-phenyl-[1, 8]naphthyridin-2(1H)-ones. These
