Synthesis of 4-(Arylmethyl)proline Derivatives

Autor: Carlotta Foletti, Helma Wennemers, Marcus Papmeyer, Simon Loosli

Publikováno v: Synlett, 30 (4)

A synthesis of 4-(arylmethyl)proline by using Suzuki cross-couplings was developed. The route permits access to a variety of 4-substituted proline derivatives bearing various aryl moieties that expand the toolbox of proline analogues for studies in c

Molecularly Defined Nanostructures Based on a Novel AAA-DDD Triple Hydrogen-Bonding Motif

Autor: Giovanni M. Pavan, Konstantin O. Zhurov, Marcus Papmeyer, Clément A. Vuilleumier, Kay Severin

Publikováno v: Angewandte Chemie International Edition. 55:1685-1689

A facile and flexible method for the synthesis of a new AAA-DDD triple hydrogen-bonding motif is described. Polytopic supramolecular building blocks with precisely oriented AAA and DDD groups are thus accessible in few steps. These building blocks we

A heterometallic macrocycle as a redox-controlled molecular hinge

Autor: Marcus Papmeyer, Kay Severin, Clément Schouwey, Rosario Scopelliti

Publikováno v: Dalton Transactions

© The Royal Society of Chemistry 2015. The ability to modify the structure of nanoscopic assemblies in a controlled fashion is an important prerequisite for the creation of functional supramolecular systems. Here we describe a heterometallic Pt2Cu2

Publikováno v: De Bo, G, Kuschel, S, Leigh, D A, Lewandowski, B, Papmeyer, M & Ward, J W 2014, ' Efficient assembly of threaded molecular machines for sequence-specific synthesis ', Journal of the American Chemical Society, vol. 136, no. 15, pp. 5811-5814 . https://doi.org/10.1021/ja5022415

We report on an improved strategy for the preparation of artificial molecular machines that can pick up and assemble reactive groups in sequence by traveling along a track. In the new approach a preformed rotaxane synthon is attached to the end of an

A scalable synthesis of 5,5′-dibromo-2,2′-bipyridine and its stepwise functionalization via Stille couplings

Autor: David A. Leigh, Steffen L. Woltering, Marcus Papmeyer, Daniel M. D'Souza

Publikováno v: Nature Protocols. 7:2022-2028

The synthesis of 5,5'-dibromo-2,2'-bipyridine and 5-bromo-2,2'-bipyridine, useful intermediates for elaboration into more complex ligands through metal-catalyzed coupling reactions, can be efficiently conducted on a multigram scale from inexpensive s

Phosphorus-Based Functional Groups as Hydrogen Bonding Templates for Rotaxane Formation

Autor: Daniel M. D'Souza, Kathleen M. Mullen, Marcus Papmeyer, David A. Leigh, Jenny K. Y. Wong, J. Derek Woollins, Andrea Altieri, Rehan Ahmed, Alexandra M. Z. Slawin

Publikováno v: Journal of the American Chemical Society. 133:12304-12310

We report on the use of the hydrogen bond acceptor properties of some phosphorus-containing functional groups for the assembly of a series of [2]rotaxanes. Phosphinamides, and the homologous thio- and selenophosphinamides, act as hydrogen bond accept

Goldberg Active Template Synthesis of a [2]Rotaxane Ligand for Asymmetric Transition-Metal Catalysis

Autor: Steven, Hoekman, Matthew O, Kitching, David A, Leigh, Marcus, Papmeyer, Diederik, Roke

Publikováno v: Journal of the American Chemical Society. 137(24)

We report on the active template synthesis of a [2]rotaxane through a Goldberg copper-catalyzed C-N bond forming reaction. A C2-symmetric cyclohexyldiamine macrocycle directs the assembly of the rotaxane, which can subsequently serve as a ligand for
