(1,3-Dioxolan-2-ylmethyl)triphenylphosphonium Bromide is used as a reactant in the synthesis of ketolides methyloxoerythromycins with antibacterial activity as highly potent against macrolide-resistant and susceptible respiratory pathogens.
Purification Methods
Wash the crystals with Et2O, dry them in a vacuum and recrystallise them from CH2Cl2/dry Et2O to give prisms m 172-174o, which is raised to 191.5-193o on drying at 56o/0.5mm. [Cresp et al. J Chem Soc, Perkin Trans 1 37 1974.]
