  • An Improved Method for the Synthesis of F-BODIPYs from Dipyrrins and Bis(dipyrrin)s 

    Lundrigan, T., Baker, A. E., Longobardi, L. E., Wood, T. E., Smithen, D. A., Crawford, S. M., ... & Thompson, A. (2012). An Improved Method for the Synthesis of F-BODIPYs from Dipyrrins and Bis (dipyrrin) s. Organic letters, 14(8), 2158-2161. DOI: 10.1021/ol300681w
    An improved methodology for the synthesis of F-BODIPYs from dipyrrins and bis(dipyrrin)s is reported. This strategy employs lithium salts of dipyrrins as intermediates that are then treated with only one equivalent of boron ...
  • Synthesis and biological evaluation of prodigiosene conjugates of porphyrin, estrone and 4-hydroxytamoxifen 

    Hawco, C. L., Marchal, E., Uddin, M. I., Baker, A. E., Corkery, D. P., Dellaire, G., & Thompson, A. (2013). Synthesis and biological evaluation of prodigiosene conjugates of porphyrin, estrone and 4-hydroxytamoxifen. Bioorganic & medicinal chemistry, 21(19), 5995-6002. DOI: 10.1016/j.bmc.2013.07.042}
    To generate the first series of prodigiosene conjugates, the tripyrrolic skeleton was appended to estrone, tamoxifen and porphyrin frameworks by way of ester linkers and various hydrocarbon chain lengths. The ability of ...
  • Use of F-BODIPYs as a protection strategy for dipyrrins: optimization of BF2 removal. 

    Smithen, D. A., Baker, A. E., Offman, M., Crawford, S. M., Cameron, T. S., & Thompson, A. (2012). Use of F-BODIPYs as a protection strategy for dipyrrins: optimization of BF2 removal. The Journal of organic chemistry, 77(7), 3439-3453. DOI: 10.1021/jo3002003
    We recently reported the first general method for the deprotection of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes (F-BODIPYs) involving a microwave-assisted procedure for the removal of the BF2 moiety, and liberation of ...
  • The Use of Tin (IV) Chloride to Selectively Cleave Benzyl Esters over Benzyl Ethers and Benzyl Amines 

    Baker, A. E., Marchal, E., Lund, K. L. A., & Thompson, A. (2014). The use of tin (IV) chloride to selectively cleave benzyl esters over benzyl ethers and benzyl amines. Canadian Journal of Chemistry, 92(12), 1175-1185. https://doi.org/10.1139/cjc-2014-0364
    Benzyl esters are cleaved upon reaction with SnCl4, resulting in isolation of the corresponding carboxylic acid. Importantly, benzyl ethers, amines and amides do not undergo debenzylation under these conditions, nor do a ...
