Abstract
Diketopyrrolopyrrole (DPP)-based conjugated copolymers are important organic semiconductors for applications in high-efficiency organic thin-film transistors (OTFTs). However, the direct application of these polymers with rigid backbones in stretchable devices has limitations. In this study, we designed and synthesized three kinds of DPPBT-based copolymers, DPPBT-A1, DPPBT-A3, and DPPBT-A5, which have amide-coupled alkylene conjugation breakers capable of hydrogen bonding. Linkers with different segment lengths were copolymerized with DPP and bithiophene (BT) backbone units. A DPP-based copolymer with alternating BT moieties, DPPBT, was synthesized as a reference fully conjugated copolymer. The synthesized polymers with freely rotational backbone linkers have sufficient flexibility to develop ordered phase domains, even in thin films, in comparison to the reference copolymer. However, the introduction of the conjugation breakers, which disconnect the intramolecular π-π overlapping, tends to decrease the hole mobility (μ) from 0.76 to 0.20 cm2 V-1 s-1 in the corresponding OTFT devices. The TFT fabricated using DPPBT-A3 showed a mobility of 0.50 cm2 V-1 s-1, and the mobility value did not show a significant change even when elongated by more than 50%. Therefore, the molecular design strategy of introducing amide-coupled alkylene conjugation breakers into conjugated polymer chains can contribute significantly to the development of high-mobility stretchable conjugated polymers in future.

Abstract
The involvement of NMDA receptors containing the GluN2B subunit in neurodegenerative disorders including Alzheimer's and Parkinson's disease renders this NMDA receptor subtype an interesting pharmacological target. The aim of this study was the bioisosteric replacement of benzene, methoxybenzene and aniline moieties of known potent GluN2B selective NMDA receptor antagonists by a thiophene ring. In a nine-step synthesis starting from commercially available propionic acid 9 the thiophene derivative 7a was obtained as a bioisostere of the potent GluN2B ligands cis-3 and trans-3. [7]Annuleno[b]thiophene 8a without a benzylic OH moiety was prepared in a six-step synthesis starting from carboxylic acid 18. 8a represents a bioisostere of potent GluN2B ligands 4 and 5. [7]Annulenothiophene 8a without a benzylic OH moiety reveals approx. 8-fold higher GluN2B affinity (K i = 26 nM) than the analogous thiophene derivative 7a with a benzylic OH moiety (K i = 204 nM). Both thiophene bioisosteres show a slight preference for GluN2B receptors over both σ receptors. The data indicate that the bioisosteric replacement of benzene or substituted benzene rings by a thiophene ring is well tolerated by the NMDA receptor. Furthermore, the benzylic OH moiety seems not to be essential for high GluN2B affinity.

Abstract
Abstract
Chemokines (chemoattractant cytokines) together with their receptors represent key players in inflammatory processes. In order to develop novel chemokine CCR2 and CCR5 receptor antagonists, 2-benz-azepin-1-one 5 was prepared, which showed promising CCR2 affinity. During the synthesis, regioisomeric bromo substituted β-keto esters 4a and 4b had to be separated. A crystal structure determination of the regioisomer 4b displayed unequivocally the bromine atom in the 7-position and the existence of 4b as the enol ester tautomer. Although the 7-membered azepine ring is rather flat, it is distorted around the 3-methylene moiety.

Abstract
Targeting CCR2 and CCR5 receptors is considered as promising concept for the development of novel antiinflammatory drugs. Herein, we present the development of the first probe-dependent positive allosteric modulator (PAM) of CCR5 receptors with a 2-benzazepine scaffold. Compound 14 (2-isobutyl-N-({[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl}phenyl)-1-oxo-2,3-dihydro-1H-2-benzazepine-4-carboxamide) activates the CCR5 receptor in a CCL4-dependent manner, but does not compete with [3H]TAK-779 binding at the CCR5. Furthermore, introduction of a p-tolyl moiety at 7-position of the 2-benzazepine scaffold turns the CCR5 PAM 14 into the selective CCR2 receptor antagonist 26b. The structure affinity and activity relationships presented here offer new insights into ligand recognition by CCR2 and CCR5 receptors.

Abstract
CCR2 and CCR5 receptors play a key role in the development and progression of several inflammatory, cardiovascular and autoimmune diseases. Therefore, dual targeting of both receptors appeals as a promising strategy for the treatment of such complex, multifactorial disorders. Herein we report on the design, synthesis and biological evaluation of benzo[7]annulene- and [7]annulenothiophene-based selective and dual CCR2 and CCR5 receptor antagonists. Intermediates were designed in such a way that diversification could be introduced at the end of the synthesis. Starting from the lead compound TAK-779 (1), the quaternary ammonium moiety was exchanged by different non-charged moieties, the 4-methylphenyl moiety was extensively modified and the benzo[7]annulene core was replaced bioisosterically by the [7]annulenothiophene system. The naphthyl derivative 9h represents the most promising dual antagonist (Ki (CCR2) = 25 nM, IC50 (CCR5) = 17 nM), whereas the 6-isopropoxy-3-pyridyl and 4-methoxycarbonylphenyl derivatives 9k and 9r show more than 20-fold selectivity for the CCR2 (Ki = 19 nM) over the CCR5 receptor.

Abstract
The first general β-selective C-H arylation of pyrroles has been developed by using a rhodium catalyst. This C-H arylation reaction, which is retrosynthetically straightforward but results in unusual regioselectivity, could result in de novo syntheses of pyrrole-derived natural products and pharmaceuticals. As such, we have successfully synthesized polycyclic marine pyrrole alkaloids, lamellarins C and I, by using this β-selective arylation of pyrroles with aryl iodides (C-H/C-I coupling) and a new double C-H/C-H coupling as key steps.

Abstract
Readily available triethylammonium 1-(2-oxoindolin-3-ylidene)-2-aroylethanethiolates are efficiently converted into a variety of fully substituted thiophene derivatives by copper(I)-catalyzed denitrogenative reactions with terminal alkynes and N-sulfonyl azides. This new reaction simultaneously installs C-N, C-S, and C-C bonds, allowing direct formation of highly functionalized thiophenes with a wide diversity in substituents in a one-pot manner. A plausible mechanism for the domino process is proposed.
