A new method for methylenecyclopentane annulation via formal [3+2] cycloaddition reaction was developed. Under the influence of Lewis acids, enol ethers and vinylsulfides were treated with I-(alkylthio)-2-(trimethylsilylmethyl)allyl esters 1a or 1b to afford methylenecyclopentanes in good yields. The reaction proceeds with almost complete regioselectivity as well as high stereoselectivity.

Alkanesulfonic acids and alkanesulfonyl chlorides, free of undesirable side products arising from side-chain chlorination, are prepared by oxidation with hydrogen peroxide of the corresponding alkanethiol, dialkyldisulfide or alkyl alkanethiolsulfonate mixed with aqueous hydrochloric acid.
