then of Ramberg-Backlund elimination to a substituted olefin. The alkylations are clean and regiospecific, often amenable to one-pot operation, and in most cases the elimination is smooth. A variety of examples is presented to establish the scope of the method, and the mechanism and stereochemistry are discussed. Nuclear Synthons. In our examination of the logic of synthesis design* we directed attention
甲磺酰三氟乙烯 (CF3S02CH2S02CH3) 被开发为一种核合成试剂,能够首先进行多种结构,例如烷基化,然后通过 Ramberg-Backlund 消除生成取代的烯烃。烷基化是干净的和区域特异性的,通常适合一锅法操作,并且在大多数情况下消除是顺利的。提供了各种示例来确定该方法的范围,并讨论了机理和立体化学。核合成器。在我们对合成设计*逻辑的检查中,我们将注意力集中在最小化步骤和主要利用构建反应的核心重要性上。这些想法的一个主要推论是多重构造的首要重要性,允许在一次操作中进行两个或更多构造。等式 1-4 中说明了该概念的典型示例,
