Recently, radical difunctionalization of the feedstock 1,3-butadiene has become an attractive strategy for increasing molecular complexity. Herein, we present a novel approach that effectively combines radical thiol-ene chemistry with TiIII catalysis to enable a three-component aldehyde allylation using 1,3-butadiene as an allyl group source under visible light conditions. This sustainable and straightforward
最近,原料 1,3-丁二烯的自由基双官能化已成为增加分子复杂性的一种有吸引力的策略。在此,我们提出了一种新方法,将自由基硫醇-烯化学与Ti III催化有效结合,在可见光条件下使用1,3-丁二烯作为烯丙基源实现三组分醛烯丙基化。这种可持续且简单的方法促进了具有卓越区域选择性和非对映选择性的多种烯丙基 1,3-硫醇的快速生产。
