4-alkenyl-1-methoxy-1,4-cyclohexadienes by tandem addition-multistep reduction of alkenyl aldehydes and ketones. Synthesis of 4-alkenyl-3-cyclohexen-1-ones by subsequent hydrolysis

A series of 4-alkenyl-1-methoxy-1,4-cyclohexadienes were prepared by a tandem addition-multistep reduction procedure. This one-pot process included the addition of 4-methoxyphenyllithium to alkenyl aldehydes and ketones, followed by multistep reduction of

Synthesis of 2-(4'-Methyl-1',3'-cyclohexadienyl)-6,10-dimethyl-5,9-undecadiene (9-Geranyl-α-terpinene)

5,5-Dimethyl-4,8-decadienal (II) on Grignard reaction with p-anisylmagnesium bromide yields the alcohol (III) which on oxidation followed by Wittig reaction with methylenetriphenylphosphorane affords the undecatriene (V).V on lithium/liquid ammonia reduction and subsequent mild hydrolysis with oxalic acid gives 2-(4'-oxo-Δ1',2'-cyclohexenyl)-6,10-dimethyl-5,9-undecadiene (VI).VI on Grignard reaction with methylmagnesium iodide yields VII which on dehydration with phosphorusoxychloride in pyridine furnishes the title compound (I).
