Zhang, Xiao-Nan published the artcileA Highly Nucleophilic Multifunctional Chiral Phosphane-Catalyzed Asymmetric Intramolecular Rauhut-Currier Reaction, Application In Synthesis of 126613-06-7, the publication is European Journal of Organic Chemistry (2012), 2012(31), 6271-6279, database is CAplus.
An asym. variant of the intramol. Rauhut-Currier (RC) reaction can be achieved using a highly nucleophilic multifunctional chiral phosphine; the corresponding cyclopentene and cyclohexene derivatives are produced in moderate to good yields and with good to excellent enantioselectivities. E.g., in presence of the chiral phosphine I, Rauhut-Currier reaction of (E,E)-II gave 96% cyclohexene derivative III (61% ee).
