New photochromic switches based on helical alkenes can quickly and efficiently be accessed by Pd-catalyzed domino reactions using a modular approach; this allows a wide variability in product formation with the advantages of a convergent synthetic route. The alkenes have been synthesized in excellent enantioselectivity and their switching properties assessed by stimulation with nanosecond laser pulses at two different wavelengths in over 1000 switching cycles.
基于螺旋烯烃的新型光致变色开关可以通过 Pd 催化的多米诺反应以模块化方法快速有效地获得；这种方法允许在产品形成方面具有广泛的可变性，同时具有收敛合成路线的优点。已经以优异的对映选择性合成了这些烯烃，并通过在两个不同波长的纳秒激光脉冲刺激下进行了超过 1000 个循环的开关测试来评估它们的开关性能。
