  • An isothiourea-catalyzed asymmetric [2,3]-rearrangement of allylic ammonium ylides 

    West, Thomas H.; Daniels, David S. B.; Slawin, Alexandra M. Z.; Smith, Andrew D. (2014-03-26) - Journal article
    Benzotetramisole promotes the catalytic asymmetric [2,,3]-rearrangement of allylic quaternary ammonium salts (either isolated or prepared in situ from p-nitrophenyl bromoacetate and the corresponding allylic amine), ...
  • A scalable, chromatography-free synthesis of benzotetramisole 

    Daniels, David Sydney Bernard; Smith, Siobhan Rose; Lebl, Tomas; Shapland, P.; Smith, Andrew David (2015-01) - Journal article
    The scalable, chromatography-free synthesis of the chiral isothiourea benzotetramisole (BTM) in two steps from commercially available materials is presented. A detailed procedure for the synthesis of both enantiomers and ...
