Procedure

The title compound was prepared in 53.9% yield following the procedure described in step 6 of method 2 for the preparation of intermediate 1, using methyl 4-oxocyclohex-1-enecarboxylate and methyl 4-oxocyclohex-2-enecarboxylate as the reactants. Methyl 4-oxocyclohex-1-enecarboxylate and methyl 4-oxocyclohex-2-enecarboxylate were prepared following the procedures described in Tet. Lett. Vol. 53, issue 7, page 819-821. m/e 287.05 (M+H)+, 2.435 min (method 8). 1H NMR (400 MHz, CHLOROFORM-d) δ 6.96 (dt, J=6.3, 1.5 Hz, 1H), 6.07 (dt, J=6.4, 1.4 Hz, 1H), 3.78 (s, 3H), 2.81-2.73 (m, 2H), 2.67-2.59 (m, 2H). 19F NMR (376 MHz, CHLOROFORM-d) δ −73.55 (s, 3F).
