Several 3-(2'-hydroxyethyl)quinolin-2(1H)-ones were prepared by the photolysis of N-aryl-4,5-dihydrofuran-3-carboxamides.The newly reported quinolonyl ethanols were converted to 2,3-dihydrofuroquinolines.

Fragmentation patterns resulting from electron impact ionization of 3-(2'-hydroxyethyl)quinolin-2(1H)-one, three of its monosubstituted derivatives and four of its disubstituted derivatives were studied.The molecular ion of quinolinone-2-ethanol undergoes initial fragmentation with the loss of OH, H2O, CO, CHO, CH2O, CH2OH, CH2=CHOH and HCNO species.The + ion is tentatively suggested to have been formed by the expulsion of H from the + ion and the + peak may be considered as diagnostic of a 2-quinolone-3-ethanol.
