The reaction of 3-phenyl-2-cyclohexen-1-one (3.0 g, 17.4 mmoles) in 10 ml of THF with lithium diisopropylamide (19.2 mmoles) followed by ethyl bromoacetate (3.5 g, 20.9 mmoles) in 10 ml of THF, at -78° C. under argon, was conducted in a similar manner to the synthesis of 6-(carbethoxymethyl)-3-methyl-2-cyclohexen-1-one described in Example II. A yield of 3.90 g (87%) of 6-(carbethoxymethyl)-3-phenyl-2-cyclohexen-1-one was obtained.
