Ring opening of the dibenzylidene derivative of pentaerythritol 12 with N-bromosuccinimide gave di-O-benzoyldibromodideoxypentaerythritol (29). Reaction of 20 and 21 with hydrogen bromide in acetic acid afforded di-O-acetyl-di-O-p-toluenesulfonyl pentaerythritol (26). Nucleophilic displacement of the tosyloxy groups in 20 by 1,2,4 triazole afforded 2-phenyl-5-(p-toluenesulfonyloxymethyl)-5-(1,2,4-triazolylmethyl)-1,3-dioxan (31) and 2-phenyl-5,5-bis(1,2,4-triazolylmethyl)-1,3-dioxan (32), and with benzotriazole gave 2-phenyl-5,5-bis(benzotriazolylmethyl)-1,3-dioxan (30). The activity of various derivatives against hepatitis B virus has been studied.
