Condensation of the isoindole–isoindoline isomers of the thieno[3′,2′:5,6]pyrimido[2,1-a]isoindol-6(10H)-one with aldehydes
摘要
The reaction of the isoindole–isoindoline isomers of the thieno[3′,2′:5,6]pyrimido[2,1-<i>ai>]isoindol-6(10<i>Hi>)-one with aldehydes gives new benzylidene thieno[3′,2′:5,6]pyrimido[2,1-<i>ai>]isoindol-6(10<i>Hi>)-one derivatives. The structures were assessed with NMR, UV spectroscopy and mass spectra.
