A new and reliable procedure for constructing five- to seven-membered carbocycles via an endo-mode ring-closing reaction of 1-phenylsulfonylallenes with a substituent that has a terminal active methine moiety at the C1-position has been developed. Trisubstituted 1-phenylsulfonylallenes underwent a similar endo-mode ring-closing reaction to produce the corresponding five- to seven-membered carbocycles
已经开发出一种新的可靠的程序,该程序通过1-苯基磺酰戊二烯与在C 1位具有末端活性次甲基部分的取代基的内模闭环反应来构建五至七元碳环。三取代的1-苯基磺酰戊二烯经历类似的内模闭环反应,以产生相应的五至七元碳环,而未实现由相应的四取代的丙二烯形成六元和七元碳环。另外,在起始烯基的烷基侧链上引入芳环使得不仅可以构建常规尺寸的碳环,而且还可以构建八元框架。
