A terpene compound having the formula (III) is produced by reacting an allylic halide having the formula (I) with a Grignard reagent having the formula (II) in the presence of anhydrous zinc chloride and a copper compound or an organic zinc halide compound having the formula (IV) in the presence of a copper compound, provided that when A-A is C-C, R is hydrogen and when A-A is C = C, X is chlorine.
具有式(III)的萜类化合物是通过具有式(I)的烯丙基卤化物与具有式(II)的格氏试剂在无水氯化锌和铜化合物存在下或具有式(IV)的有机卤化锌化合物在铜化合物存在下反应制得的,条件是当 A-A 为 C-C 时,R 为氢,当 A-A 为 C = C 时,X 为氯。

New information is discussed concerning the protic and Lewis acid-initiated electrophilic cyclization reaction of alpha-monoterpenols and their acetates; the distinguishing feature of these reactions is their termination by isopropenyl residues in these molecules. The reactions have been found to be general in nature, given additional functionalization of the terminator by chloro-, sulfonyl, sulfonylmethyl, or ester substituents. Cyclization of these linear substrates has also been shown to provide a convenient method for the synthesis of dimethylvinylcyclohexene derivatives and related cyclohexanediols, which are not readily available by other methods.
