    Arylation of Lithium Sulfinates with Diaryliodonium Salts: A Direct and Versatile Access to Arylsulfones
    摘要:
    An efficient, transition-metal-free arylation of lithium sulfinates, which are readily accessible from reactions of organolithium reagents with sulfur dioxide, is described. Based on this method, a practical protocol for the direct transformation of (hetero)arenes and (hetero)aromatic halides into diarylsulfones was developed.

    Pd-catalyzed asymmetric synthesis of allylic tert-butyl sulfones and sulfides: Kinetic resolution of the allylic substrate by a chiral Pd-complex
    摘要:
    The acyclic and cyclic allylic tert-butyl sulfones 3, ent-3, 11a, 11b and 15a-c of 89-98% ee were synthesized in 40-92% yield by a Pd-catalyzed reaction of the respective allylic acetates and carbonates rac-1a, rac-1b, rac-10a, rac-10b and rac-14a-c with LiO(2)St-Bu in the presence of the chiral ligands 2a, ent-2b and 12. Formation of the n-butyl sulfones 13a and 13b of 95% ee was observed. Reactions of rac-1a and 1b/ent-1b with LiO(2)St-Bu in the presence of 2a and ent-2b, respectively, in THF under heterogeneous conditions were accompanied by a kinetic resolution of the allylic substrates. The faster reacting allylic substrate and the preferentially formed sulfone had the same absolute configuration. The allylic tert-butyl sulfide 17 of 92% ee was obtained in 63% yield by the Pd-catalyzed reaction of rac-1b with Me(3)SiSt-Bu in the presence of ent-2b. (C) 1998 Elsevier Science Ltd.
