1-(Trimethoxymethyl) cyclohexene (11) was synthesized in three steps f
rom N-methyl-N-phenylcyclohex-1-ene-1-carboxamide (8). Reaction of the
alpha,beta-unsaturated ortho ester (11) with sodium hydride and N-met
hylaniline gave a 1 : 1 mixture of methyl cyclohex-1-ene-1-carboxylate
(15) and N,N-dimethylaniline. Treatment of (11) with 3-methoxyphenol
gave 1-[dimethoxy(3'-methoxyphenoxy)methyl]cy (10) which underwent the
rmolysis at 250 degrees to give 1,3-dimethoxybenzene (16) and methyl c
yclohex-1-ene-1-carboxylate (15).
