A catalytic multicomponent (4+2)–(2+2) cascade cycloaddition process assembling three different substances has been developed. The process is able to rapidly provide a highly substituted bicyclo[4.2.0]octane skeleton from a 2-siloxydiene and two molecules of α,β-unsaturated carbonyl partners. The MCR process is accompanied by stereoselective formation of four carbon–carbon bonds and four stereogenic
已开发出一种可催化的多组分(4 + 2)–(2 + 2)级联环加成工艺,可组装三种不同的物质。该方法能够从2-甲
硅烷氧基二烯和两个α,β-不饱和羰基分子分子中快速提供高度取代的
双环[4.2.0]辛烷骨架。MCR过程伴随着一次操作中四个碳-碳键和四个立体中心的立体选择性形成。
