A stereoselective allylic alkylation of isatin-derived Morita–Baylis–Hillman (MBH) carbonates with nitroalkanes has been developed. In the presence of 10 mol % β-isocupreidine (β-ICD), 3,3′-disubstituted oxindoles were prepared with moderate diastereoselectivities and excellent enantioselectivities.
已经开发了使用硝基烷烃对源自靛红的Morita–Baylis–Hillman(MBH)碳酸盐进行立体选择性烯丙基烷基化的方法。在10mol%的β-异iso啶(β-ICD)的存在下,制备了具有适度的非对映选择性和优异的对映选择性的3,3′-二取代的羟吲哚。
