The invention relates to a preparation method of 3-acetylcyclopentyl methyl formate. The preparation method comprises the following steps: after mixing 3-methylene-2-norborneol ketone and methylbenzene, adding methyl alcohol, and in 0 DEG C, adding concentrated sulfuric acid, in a condition of warming to 15-25 DEG C, adding hydrogen peroxide, performing a reaction, ending the reaction, cooling, and removing excessive raw materials, after washing, performing organic phase reduced pressure distillation to obtain the 3-acetylcyclopentyl methyl formate. The provided synthetic method is easy to obtain starting raw materials, low in cost, and high in mole yield (64% or more). After washing and extracting, the product purity is high (94% or more).

Chiral spirocyclic dioxinones having an ω-alkenyl group at 3-position were synthesized and their intramolecular photocycloaddition reactions were examined.The results not only provide enantioselective synthetic route to 2S-acetonylcyclohexanecarboxylic acids but also clarify the reason why these dioxinones exhibit remarkable diastereofacial selectivities in both intra- and intermolecular photocycloaddition reactions.
