发展了一种室温(3+2)环加成反应合成高取代二氢噻吩衍生物的方法。通过利用结构独特的硫代羰基叶立德,这些传统的高能量中间体的反应性可以被调制,使合成有用的转化在温和的条件下进行。
A room-temperature (3+2) cycloaddition sequence for the synthesis of highly substituted dihydrothiophene derivatives has been developed. By utilizing structurally unique thiocarbonyl ylides, the reactivity of these traditionally high-energy intermediates can be modulated, enabling a synthetically useful transformation to proceed under mild conditions.
