|Title:||Fused bispentacenequinone and its unexpected Michael addition||Authors:||Zhang, X.
|Issue Date:||3-Sep-2010||Citation:||Zhang, X., Li, J., Qu, H., Chi, C., Wu, J. (2010-09-03). Fused bispentacenequinone and its unexpected Michael addition. Organic Letters 12 (17) : 3946-3949. ScholarBank@NUS Repository. https://doi.org/10.1021/ol101720e||Abstract:||Fused bispentacenequinone 2 was synthesized by photocyclization of bispentacenequinone 1. Unusual regioselective Michael addition was observed for 2 when excess aryl Grignard reagent was used. Subsequent acidification and oxidation in air gave diaryl-substituted bispentacenequinone 3. Tetra-aryl-substituted fused bispentacenequinone 4 was obtained from 3 after the second Michael addition followed by oxidation in air. © 2010 American Chemical Society.||Source Title:||Organic Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/76235||ISSN:||15237060||DOI:||10.1021/ol101720e|
