The copper‐catalysed conjugate addition of trialkylaluminium and dialkylzinc reagents to polyconjugated nitroolefins (nitrodiene and nitroenyne derivatives) is reported. A reversed Josiphos ligand L7 allows for the selective 1,4‐ or 1,6‐addition with high enantioselectivities.
据报道,铜催化将三烷基铝和二烷基锌试剂共轭加成到共轭硝基烯烃(硝基二烯和亚硝基炔衍生物)中。反向的Josiphos配体L7可实现对映体选择性高的选择性1,4或1,6加成。
