Oxoiminium salts 11 a-e and 13 a-e have been prepared from the ο-chloroketones 9 a-e by oximation via the cyclic oxime ethers 10 a-e and the cyclic imine oxides 12 a-e, followed by alkylation with "Meerwein salt".The deprotonation reaction of 11 a-e and 13 a-e yields, via the regioselectively prepared intermediates 14 a-e and 17 a-e, the α, β-unsaturated imines 15 a-e and the cyclic imines 18 a-e, respectively.
