Commercial polyether polyols are usually obtained by the ring-opening polymerization of epoxides or tetrahydrofuran. 2-Methyl-tetrahydrofuran (2-MeTHF) could be an alternative bio-based building block for the synthesis of these polyols. Although 2-Me

In this manuscript we describe how, by taking a systems approach, complex energy landscapes of supramolecular assemblies can be navigated using stoichiometry to control, with remarkable selectivity, which assembly gets populated. The perhaps counteri

Regio- and Enantioselective Copper-Catalyzed Allylic Alkylation of Ortho-Substituted Cinnamyl Bromides with Grignard Reagents
Autor: Martín Fañanás-Mastral, Theodora D. Tiemersma-Wegman, Ben L. Feringa, Nathalie C. van der Molen
Publikováno v: Journal of Organic Chemistry, 80(10), 4981-4984. AMER CHEMICAL SOC INC
A highly efficient method for the copper-catalyzed asymmetric allylic alkylation of ortho-substituted cinnamyl bromides with Grignard reagents is reported. The use of a catalytic system comprising CuBr center dot SMe2 and TaniaPhos as chiral ligands

Effect of increased serotonin levels on [F-18] MPPF binding in rat brain
Autor: Fokko-J Bosker, Johan A. den Boer, Theodora D Tiemersma-Wegman, Joanna I Udo de Haes, Folkert Postema, Thomas I. F. H. Cremers
Publikováno v: Neuropsychopharmacology, 30(9), 1624-1631. Nature Publishing Group
[F-18]MPPF is a selective serotonin-1A (5-HT1A) receptor antagonist and may be used to measure changes in the functional levels of serotonin (5-HT). The technique is based on the assumption that the injected radiolabeled ligand competes for the same

Enantioselective synthesis of beta(2)-amino acids using rhodium-catalyzed hydrogenation
Autor: Ben L. Feringa, Adriaan J. Minnaard, Laurent Lefort, Barbara Procuranti, Rob Hoen, Johannes G. de Vries, Theodora D. Tiemersma-Wegman
Publikováno v: Organic & Biomolecular Chemistry, 5(2), 267-275. ROYAL SOC CHEMISTRY
A series of protected beta(2)-dehydroamino acids has been prepared in three steps from commercially available starting materials in good yields. These were used as substrates in rhodium-catalyzed asymmetric hydrogenation applying a mixed ligand syste
