A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Safety of (R)-[1,1′-Binaphthalene]-2,2′-diol, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 18531-94-7, Name is (R)-[1,1′-Binaphthalene]-2,2′-diol, molecular formula is C20H14O2. In a Article, authors is Guan, Xiao-Yang，once mentioned of 18531-94-7
A series of chiral sterically congested phosphane-amide bifunctional Lewis bases L1-L3 have been successfully synthesized and their application in asymmetric aza-Morita-Baylis-Hillman (aza-MBH) reactions of N-sulfonated imines with activated olefins such as methyl and ethyl vinyl ketone has been investigated under mild conditions. The corresponding aza-MBH adducts can be obtained in good-to-excellent yields (up to 98%) and moderate-to-good enantioselectivities (up to 91 or 93%ee) in dichloromethane at room temperature (20C) with these novel chiral bifunctional phosphane Lewis bases.
