A convergent, multistep protocol was employed for the synthesis of a Janus-type multivalent donor-acceptor system. The synthetic approach is based on a Sonogashira cross-coupling of two differently ferrocene-(Fc) substituted dendrons and a final sixfold [

Three-component asymmetric catalytic ugi reaction - Concinnity from diversity by substrate-mediated catalyst assembly

supporting information, p. 3436 - 3441 (2014/04/03)
The first chiral catalyst for the three-component Ugi reaction was identified as a result of a screen of a large set of different BOROX catalysts. The BOROX catalysts were assembled in situ from a chiral biaryl ligand, an amine, water, BH3×SMe2, and an alcohol or phenol. The catalyst screen included 13 different ligands, 12 amines, and 47 alcohols or phenols. The optimal catalyst system (LAP 8-5-47) provided α-amino amides from an aldehyde, a secondary amine, and an isonitrile with excellent asymmetric induction. The catalytically active species is proposed to be an ion pair that consists of the chiral boroxinate anion and an iminium cation. Harmonious arrangement of parts: A screen of BOROX catalysts that were generated in situ from 13 different ligands and 47 alcohols led to the identification of an effective combination for the catalytic asymmetric three-component Ugi reaction. Experimental results suggest that the catalyst is a chiral polyborate anion, which then forms an ion pair with the iminium cation that is generated from aldehyde and secondary amine.
Mixed-transition-metal acetylides: Synthesis and characterization of complexes with up to six different transition metals connected by carbon-rich bridging units
Packheiser, Rico,Ecorchard, Petra,Rueffer, Tobias,Lang, Heinrich
experimental part, p. 4948 - 4960 (2009/04/16)
The synthesis and reaction chemistry of heteromultimetallic transition-metal complexes by linking diverse metal-complex building blocks with multifunctional carbon-rich alkynyl-, benzene-, and bipyridyl-based bridging units is discussed. In context with this background, the preparation of [1-{(η2-dppf)(η5-C5H 5)RuC=C)-3-{(tBu2bpy)(CO)3ReC≡C}-5- (PPh2)-C6H3] (10) (dppf=1,1′- bis(diphenyl-phosphino)ferrocene; tBu2bpy = 4,4′-diferi-butyl- 2,2′-bipyridyl; Ph = phenyl) is described; this complex can react further, leading to the successful synthesis of heterometallic complexes of higher nuclearity. Heterotetrametallic transition-metal compounds were formed when 10 was reacted with [((η5-C5Me5)-RhCl 2}2] (18), [(Et2S)2PtCl2] (20) or -(tht)AuC≡C-bpy] (24) (Me = methyl; Et = ethyl ; tht = tetrahydrothiophene ; bpy = 2,2′-bipyridyl-5-yl). Complexes [1-((η2-dppf)(η5-C5H 5)RuC=C}-3-{(tBu2bpy)(CO)3ReC≡C)-5- (PPh2RhCl2(η5-C5Me 5)C6H3] (19), [{1-[(η2-dppf) (η5-C5H5)RuC=C]-3-[(tBu2-bpy) (CO).,ReC=-C]-5-(PPh2)C6H3}2- PtCl2] (21), and [1-((η2-dppf)(η5- C5H5)-RuC≡C}-3-((tBu2bpy)(CO) 3ReC≡C)-5-(PPh2AuC≡C-bpy)C6H 3] (25) were thereby obtained in good yield. After a prolonged time in solution, complex 25 undergoes a transmetallation reaction to produce [(tBu2bpy)(CO)3ReC≡C-bpy] (26). Moreover, the bipyridyl building block in 25 allowed the synthesis of Fe-Ru-Re-Au-Mo- (28) and Fe-Ru-Re-Au-Cu-Ti-based (30) assemblies on addition of [(nbd)Mo(CO) 4] (27), (nbd = 1,5-norbornadiene), or [{[Ti](μ-σ,π- C≡CSiMe3)2)Cu(N=CMe)]-[PF6] (29) ([Ti] = (η5-C5H4SiMe3)2Ti) to 25. The identities of 5, 6, 8, 10-12, 14-16, 19, 21, 25, 26, 28, and 30 have been confirmed by elemental analysis and IR, 1H, 13C{ 1H}, and 31P{1H} NMR spectroscopy. From selected samples ESI-TOF mass spectra were measured. The solid-state structures of 8, 12, 19 and 26 were additionally solved by single-crystal X-ray structure analysis, confirming the structural assignment made from spectroscopy.
Synthesis of a Hexagonal Nanosized Macrocyclic Fluorophore with Integrated Endotopic Terpyridine Metal-Chelation Sites
Baxter, Paul N. W.
, p. 5011 - 5022 (2007/10/03)
A rigid nanosized hexagonal phenylethynyl cyclophane 5 has been prepared, which incorporates two 2,2′:6′,2″-terpyridines as integral structural units, for the purpose of binding metal ions. Macrocycle 5 was obtained by a 14-step synthesis in an overall yield of 11%, and was characterised by spectroscopic techniques. The efficiency and ease of all transformations, and the relatively enhanced yield of the final macrocyclisation suggests that the entire synthetic pathway should be amenable to scale-up. Cyclophane 5 possesses four bulky triisopropylsilyl(TIPS) -protected ethyne substituents which serve a dual role. Firstly, they solubilise the structure thereby facilitating purification and subsequent handling. Secondly, they enable post-synthetic modification in which additional functionality may be attached to the periphery of the ring. Significantly, 5 was found to be a fluorescent chromophore, and may therefore potentially function as a new sensory platform for the detection of metal ions and H-bond donating biological substrates. The structurally well-defined nanosized morphology of 5, coupled with its interesting spectroscopic properties, supports the expectation that 5 and related architectures will attain a wealth of future applications within the developing fields of nanochemistry and nanoscience.
