添加 de Michael de Differents 亲核试剂 sur le phenylsulfonyl-2 cyclohexadiene-1,3、le phenylsulfonyl-3 butadiene-1,3 和 le phenylsulfonyl-2 pentadiene-1,3。Reaction de Diels-Alder entre plusieurs phenylsulfonyl-2 dienes-1,3 和某些 dienophiles comme l'丙烯酸酯 demethyle (les enamines et les ethers d'enol donnent des reactors hautement regioselectives)
The monoterpene isolated from Mentha haplocalyx, 3,3,5-trimethyl-2-oxabicyclo[2.2.2]oct-5-en-4-ol, was synthesized according to its proposed structure. However, the NMR data of the synthetic sample were not in agreement with those reported for the natural product. After considerable efforts, the genuine structure was confirmed as (1R*,2R*)-4-(1'-hydroxy-1'-methylethyl)-1-methylycyclohex-3-ene-1,2-diol
