(+)-Salsolidine in Synthesis of 5,6-Dihydropyrrolo[2,1-a]Isoquinolines
摘要
8,9-Alkoxy-1-(benzyl)-2,3-bis(phenyl)-5,6-dihydropyrrolo[2,1-a]isoquinolines, structural analogs of cytotoxic marine lamellarin-type alkaloids, were synthesized in one step from the isoquinoline alkaloid salsolidine and aromatic aldehydes (4-methoxy-, 4-bromo-, and benzaldehyde) in 56–64% yields. The structures of the synthesized compounds were established using NMR spectroscopic and mass spectrometric data.
