    Chiral Pd-catalyzed trifluoropyruvate-ene reactions with steroidal side chains for late-stage fluoromethyl-functionalization: remarkably high agonist activities of ene products even in low VDR binding affinity
    摘要:
    The highly enantioselective trifluoropyruvate-ene reactions of chiral steroid side chain olefins were achieved by dicationic palladium complexes as chiral Lewis acid catalysts to give steroidal ene-products in high diastereoselectivity. The ene products exhibited remarkably high agonist activities for human osteocalcin even in low vitamin D receptor binding affinity for human vitamin D hormone receptor. (C) 2015 Elsevier Ltd.

    公开(公告)日:2009-12-17
    An optically active, fluorine-containing carbonyl-ene product is produced by reacting a fluorine-containing α-ketoester with an alkene in the presence of a transition metal complex having an optically active ligand. There are Mode 1 of conducting this reaction in the absence of reaction solvent, Mode 2 of conducting this reaction in a solvent that is low in relative dielectric constant, and Mode 3 of conducting this reaction in a halogenated hydrocarbon-series solvent. In each of these three modes, it is possible to produce the optically active, fluorine-containing carbonyl-ene product with low cost.

    An efficient asymmetric carbonyl-ene reaction of trifluoropyruvate catalyzed by chiral Pd(II)/(S)-SunPhos complex was developed. A series of optically active homoallylic alcohols containing a CF3 group were obtained with high yields and excellent ee under mild conditions. Particularly, the reaction of isobutylene and trifluoropyruvate gave the desired product (90% yield, 98% ee) with catalyst loading
