Side-bridged cyclam transition metal complexes bearing a phenolic ether or a phenolate pendent arm
Mewis, Ryan E.,Archibald, Stephen J.
, p. 578 - 589 (2019/09/03)
Side-bridged cyclam transition metal complexes (M = Ni(II), Cu(II) and Zn(II)) bearing a phenolic ether or phenolate pendent arm have been synthesised. For [NiL1]+ and [CuL1]+, evidence for a phenoxyl radical wa
Synthesis and structural characterization of a highly substituted triazine ring comprising a sterically flexible methylene linker and coordinating substituents

The efficient multi-step, large-scale synthesis, spectroscopic characterization and solid-state molecular structure of a new type of three-fold functionalized, sterically demanding triazine is reported. The aromatic heterocycle 6,6′,6′'-((1,3,5-triazine-2,4,6-triyl)tris(methylene))tris(2,4-di-tert-butylphenol) possesses three 2,4-di-tert-butylphenol synthons bound to the 1,3,5-triazine ring via synthetically challenging methylene linkages in the 2,4,6 positions. The key to success was found in the generation of a highly reactive imidate hydrochloride salt, namely ethyl 2-(3,5-di-tert-butyl-2-methoxyphenyl)acetimidate hydrochloride, that readily undergoes cyclotrimerization. The reported preparation opens new perspectives in the design and synthesis of novel triazine molecules bearing flexible and sterically demanding functionalized groups for various applications.
Synthesis of differently substituted tacn-based ligands: Towards the control of solubility and electronic and steric properties of uranium coordination complexes
Nizovtsev, Alexey V.,Scheurer, Andreas,Kosog, Boris,Heinemann, Frank W.,Meyer, Karsten
, p. 2538 - 2548 (2013/07/11)
Starting from phenols R1,R2ArOH (5) and the anisole derivative 3,5-di-tert-butyl-2-methoxybenzyl bromide (13), a series of new tacn-based ligands (R1,R2ArOR3)3tacn (2) have been synthesized with substituents of
Efficient synthesis of 2-substituted imidazoles by palladium-catalyzed cross-coupling with benzylzinc reagents
Utas, Josefin E.,Olofsson, Berit,?kermark, Bj?rn
, p. 1965 - 1967 (2008/02/08)
Substituted benzylzinc reagents have been used in novel cross-coupling reactions with 2-iodo imidazoles to form compounds containing both a phenol and an imidazole moiety. The intramolecular hydrogen-bonding properties of these compounds were subsequently studied. Georg Thieme Verlag Stuttgart.
NITROGENOUS CYCLIC KETONE DERIVATIVE, PROCESS FOR PRODUCING THE SAME, AND USE

Page 66, (2010/02/08)
A novel compound represented by the formula (I): wherein rings A and B each represents an optionally substituted aromatic ring, or rings A and B may be bonded to each other through linking between bonds or substituents thereof to form a ring; ring C represents a nitrogenous saturated heterocycle optionally having one or more substituents besides the oxo (provided that 2,3-dioxopyrrolidine ring is excluded); R1 represents hydrogen, an optionally substituted hydrocarbon group, or an optionally substituted heterocyclic group; and-------- indicates a single bond or a double bond. It has high antagonistic activity against a tachykinin receptor, especially an SP receptor.
