Efficient syntheses and antimicrobial activities of new thiophene containing pyranone and quinolinone derivatives using manganese(iii) acetate: the effect of thiophene on ring closure-opening reactions
Özgür, Mehtap; Yılmaz, Mehmet; Nishino, Hiroshi; Avar, Eda Çınar; Dal, Hakan; Pekel, A. Tarık; Hökelek, Tuncer (Royal Soc Chemistry, 2019)The syntheses of a new series of pyranones, namely, fused pyranones and quinoline-based dihydrofurans, accompanied by 3-alkenyl-substituted structures were investigated. The products were regioselectively formed by ... -
