Abstract

Results The immediate precursors to the oxime ethers were the carbonyl compounds 6–8 These were made in 54–78% yield by the known displacement of halide ion from the ortho- halogenocarbonyl compounds 9a, 10b and 11b respectively (see Experimental section). In turn, the oxime ethers 12–14 were obtained in 60–67% yield by condensation of the aldehyde 6 or ketones 7 or 8 with O-methylhydroxylamine in ethanol or in a mixture of ...
