Solvolytic rearrangement of tosylates of 3-alkyl(aryl)-benzofuryl-2-alkyl ketoximes and 2-substituted(and unsubstituted)benzofuryl-3-methyl ketoximes with aqueous methanol depends upon their configurations.The tosylates of 2-ethyl(benzyl)benzofuryl-3-methyl ketoximes obtained in alkaline medium do not undergo solvolytic rearrangement under similar conditions.The isomerisation of anti-isomers of the above mentioned ketoximes to syn-forms with hydrogen chloride is unsuccesful.The configurations of syn- and anti-isomers of benzofuryl-2-alkyl(aryl) ketoximes have been studied by PMR spectroscopy.
