Synthesis of tertiary amides RC(O)NR₁R₂ [R = Ph, 4-MeC₆H₄, 4-PhC₆H₄, etc.; R¹ = R² = Et, n-Pr; R¹R² = CH₂(CH₂)₃CH₂] via iridium photocatalyzed amidation of carboxylic acids and tertiary amines through C-N bond cleavage was reported. A wide scope of structurally diverse carboxylic acids participated smoothly in the reaction, providing the desired tertiary amides with moderate-to-good yields (up to 93% yield).

Focal adhesion kinase (FAK) is a tyrosine kinase with prominent roles in protein scaffolding, migration, angiogenesis, and anchorage-independent cell survival and is an attractive target for the development of cancer therapeutics. However, current FAK inhibitors display dual kinase inhibition and/or significant activity on several kinases. Although multi-targeted activity is at times therapeutically advantageous, such behavior can also lead to toxicity and confound chem.-biol. studies. We report a novel series of small mols. based on a tricyclic pyrimidothiazolodiazepinone core that displays both high potency and selectivity for FAK.

Grandes Reyes, Carlos Fitzgerald;Chen, Sung-Po R.;Bobrin, Valentin A.;Jia, Zhongfan;Monteiro, Michael J. research published 《 Temperature-Induced Formation of Uniform Polymer Nanocubes Directly in Water》, the research content is summarized as follows. Conventional self-assembly methods of block copolymers in cosolvents (i.e., usually water and organic solvents) has yet to produce a pure and monodisperse population of nanocubes. The requirement to assemble a nanocube is for the second block to have a high mol. weight However, such high mol. weight block copolymers usually result in the formation of kinetically trapped nanostructures even with the addition of organic cosolvents. Here, we demonstrate the rapid production of well-defined polymer nanocubes directly in water by utilizing the thermoresponsive nature of the second block (with 263 monomer units), in which the block copolymer was fully water-soluble below its lower critical solution temperature (LCST) and would produce a pure population of nanocubes when heated above this temperature Incorporating a pH-responsive monomer in the second block allowed us to control the size of the nanocubes in water with pH and the LCST of the block copolymer. We then used the temperature and pH responsiveness to create an adaptive system that changes morphol. when using a unique fuel. This fuel (H₂O₂ + MnO₂) is highly exothermic, and the solution pH increases with the consumption of H₂O₂. Initially, a nonequilibrium spherical nanostructure formed, which transformed over time into nanocubes, and by controlling the exotherm of the reaction, we controlled the time for this transformation. This block copolymer and the water-only method of self-assembly have provided some insights into designing biomimetic systems that can readily adapt to the environmental conditions.

The synthesis and use of the first examples of unsym., mixed phosphine donor tripodal NPP₂‘ ligands N(CH₂CH₂PR₂)₂(CH₂CH₂PPh₂) are presented. The ligands are synthesized via a convenient, one pot reductive amination using 2-(diphenylphosphino)ethylamine and various substituted phosphonium dimers in order to introduce mixed phosphine donors substituted with P/P’, those being Ph/Cy (2), Ph/ⁱPr (3), Ph/ⁱBu (4), Ph/o-Tol (5), and Ph/p-Tol (6). Addnl., authors have developed the first known synthesis of a sym. tripodal NP₃ ligand N(CH₂CH₂PⁱBu₂)₃ using bench safe ammonium acetate as the lone nitrogen source (7). This new protocol eliminates the use of extremely dangerous nitrogen mustard reagents typically required to synthesize NP₃ ligands.

Their previously reported complex FeCl₂(P₂NN’-Ph) undergoes double halide abstraction with NaBPh₄ in the presence of the coordinating solvent to give [Fe(NCMe)₂(P₂NN’-Ph)][BPh₄]₂ (12). Ligand 3 can be coordinated to FeCl₂, and upon sequential halide abstraction, treatment with NaBH₄, and exposure to an atm. of dinitrogen, the dinitrogen hydride complex [Fe(H)(NPP₂‘-ⁱPr)(N₂)][BPh₄] (13) is isolated. Sym. NP₃ ligand 7 can also be coordinated to FeCl₂ and, upon exposure to an atm. of CO(g), selectively forms [FeCl(NP₃)(CO)][BPh₄] (14) after salt metathesis with NaBPh₄. Complex 14 can be treated with an excess of NaBH₄ to give the hydride complex [Fe(H)(NP₃)(CO)][BPh₄] (15), which can further be deprotonated/reduced to the Fe(0) complex Fe(NP₃)(CO) (16) upon treatment with an excess of KH. The synthesis of novel unsym. tripodal mixed phosphine donor NPP₂‘ ligands is reported. These are used to synthesize a range of iron complexes. A sym. tripodal NP₃ ligand is made from ammonium acetate and is used to synthesize the first Fe(0) NP₃ complex among others.

Govindarajan, Sudhanva R.;Jain, Tanmay;Choi, Jae-Won;Joy, Abraham;Isayeva, Irada;Vorvolakos, Katherine research published 《 A hydrophilic coumarin-based polyester for ambient-temperature initiator-free 3D printing: Chemistry, rheology and interface formation》, the research content is summarized as follows. Initiator-free, photocurable, low-toxicity, viscoelastic polymer inks are attractive materials for creating low-modulus 3D-printed elastomeric biomedical constructs. In this work, we describe the synthesis, characterization, and 3D printing/crosslinking of a hydrophilic coumarin-PEG polyester (CPP). The viscoelastic CPP melt can be extruded at room temperature and deposited into layer-by-layer patterns. Upon UV irradiation, the coumarin pendant groups undergo [2 + 2] photocyclization, creating a thermoset network without the use of monomers, photoinitiators or propagating radicals. Voxel-voxel adhesion experiments between crosslinked and uncrosslinked material were performed to examine interfacial dynamics in a native, unperturbed state, and various attempts at 3D printing were made to assess the impact of printing conditions on the ultimate printed structure. Rheol. anal. indicates a transition point where elastic behavior overtakes viscous behavior at increasing shear rate. It is hypothesized that this transition point corresponds with changes in interface formation from “sticky” to “bouncy” behavior in voxel-voxel adhesion and 3D printing processes. Tensile-mode dynamic mech. anal. (DMA) and X-Ray microtomog. (microCT) experiments reveal interfacial defect accumulation that results in deterioration of macroscopic structural and mech. properties.
