contemporary organic synthesis relies on transformations that are driven by the intrinsic, so‐called “natural”, polarity of chemical bonds and reactive centers. The design of unconventionally polarized synthons is a highly desirable strategy, as it generally enables unprecedented retrosynthetic disconnections for the synthesis of complex substances. Whereas the umpolung of carbonyl centers is a well‐known
当代许多有机合成都依赖于化学键和反应中心固有的,所谓的“天然”极性驱动的转变。非常规极化合成子的设计是非常需要的策略,因为它通常能够实现复杂物质合成的空前的逆合成断开。羰基中心的空位化是众所周知的策略,而羰基α位的极性反转要少得多。在本文中,我们报告了一种新型亲电子en烯的设计及其在高效和化学选择性,无金属的氧化C-C偶联中的应用。
