Cycloaddition reactions of the reactive intermediates obtained from N-(2-chloroethylidene)-cyclohexylamine N-oxide (2) in the presence of AgBF4 in 1,2-dichloroethane at 0 deg C with the enol acetates 6a-f are highly regioselective and stereoselective and yield the compounds 9a-d.The not isolated iminium salts 7a-f and 8e-f react with KCN in water in high stereoselectivity to give the 1,2-oxazine derivates 9a-f and 10e-f.
