The reaction of 3,3-bis(methylsulfanyl)-2-phenylsulfonylacrylonitriles (1a,b) with 2-pyridylacetonitrile (2a) in the presence of potassium carbonate as a base in DMSO afforded 4-imino-2-methylsulfanyl-3-phenylsulfonyl-4H-quinolizine-1-carbonitriles (3a,b). The methylsulfanyl group at the 2-position of 3a,b was readily removed under methanol reflux conditions to afford 4-imino-3-phenylsulfonyl-4H-quinolizine-1-carbonitriles (4a,b) in good yields. Alkyl 3-phenylsulfonyl-4H-quinolizine-1-carboxylates (4c-f) were directly synthesized from sulfonyl ketene dithioacetal (1a,b) with alkyl 2-pyridylacetates (2b,c) and involved desulfanylation by simple hydrolysis. In addition, the fluorescent properties of these compounds were investigated.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"European Journal of Organic Chemistry, 2009(33), pp.5847-5853; 2009","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley-VCH Verlag GmbH & Co.
