Substituted .gamma.-butyrolactones. Part 32. Ring construction using 3-(arylmethylene)-2,4(3H,5H)-furandione: synthesis of pyrazolones and furo[3,4-c][1,5]benzothiazepinones
Tetronic acid in reaction with aromatic aldehydes and 2-naphthylamine. Investigation of fluorescent and nonlinear-optical characteristics of compounds obtained
摘要:
By Knoevenagel condensation and by three-component condensation 3-arylmethylenetetrahydrofuran-2,4-diones and previously unknown 8,11-dihydro-11-arylbenzo[f]furo[3,4-b]quinolin-10(7H)-ones were respectively synthesized. The luminescent spectra and nonlinear-optical characteristics of compounds obtained were investigated.
