catalyzed reaction of 5,5-dimethyl-3-merca-ptocyclohex-2-enone with a number of 1-aryloxy-4-chlorobut-2-ynes. The sulfides are oxidized with 1 equiv. of m-chloroperoxybenzoic acid and the resulting sulfoxides are then stirred at r.t. for 6–8 h to give 2-aryloxymethyl-3-(m-chlorobenzoyloxy)-6,6-dimethyl-5,6,7-trihydro benzo(b)thiophene-4-ones in 70–80% yield.
通过3,5-二甲基-3-的相转移催化反应,以80-90%的产率合成了许多3-(4'-芳氧基丁-2'-炔基)硫基5,5-二甲基环己基-2-烯酮。巯基对环己基-2-烯酮,带有多个1-芳氧基-4-氯丁-2-炔基。硫化物被1当量氧化。的米氯过氧酸,将所得亚砜中在室温然后搅拌6-8小时,得到2-芳氧基-3-(米-chlorobenzoyloxy)-6,6-二甲基-5,6,7-三氢苯并(b)噻吩-4-酮,产率70-80%。
