Mitogen-activated protein kinase-interacting kinases (MNKs) and provirus integration in maloney murine leukemia virus kinases (PIMs) are downstream enzymes of cell proliferation signaling pathways associated with the resistance of tyrosine kinase inhibitors. MNKs and PIMs have complementary effects to regulate cap-dependent translation of oncoproteins. Dual inhibitors of MNKs and PIMs have not been developed. We developed a novel 4,6-disubstituted pyrido[3,2-d]pyrimidine compound 21o with selective inhibition of MNKs and PIMs. The IC50’s of 21o to inhibit MNK1 and MNK2 are 1 and 7 nM and those to inhibit PIM1, PIM2, and PIM3 are 43, 232, and 774 nM, respectively. 21o inhibits the growth of myeloid leukemia K562 and MOLM-13 cells with GI50’s of 2.1 and 1.2 μM, respectively. 21o decreases the levels ofp-eIF4E andp-4EBP1, the downstream products of MNKs and PIMs, as well as cap-dependent proteins c-myc, cyclin D1, and Mcl-1. 21o inhibits the growth of MOLM-13 cell xenografts without causing evident toxicity. 21o represents an innovative dual MNK/PIM inhibitor with a good pharmacokinetic profile.

Iridium-catalyzed, ligand-controlled directed alkynylation and alkenylation of arenes with terminal alkynes
Sun, Xin,Zhao, Wei,Li, Bi-Jie
supporting information, p. 1298 - 1301 (2020/02/04)
We report iridium-catalyzed C-C formation between benzamides and terminal alkynes. With the choice of a suitable ligand, a C-H alkynylation or alkenylation product could be obtained selectively. The directed C-H alkynylation proceeded without the need for an external oxidant, while the directed C-H alkenylation likely involves an unusual vinylidene mechanism. This divergent reactivity provides access to both alkynylation and alkenylation products from the same set of starting materials.

Conversion of a wide range of N-Boc amides to aryl ketones was achieved with Grignard reagents via chemoselective C(O)-N bond cleavage. The reactions proceeded under catalyst-free conditions with different aryl, alkyl, and alkynyl Grignard reagents. α-Ketoamide was successfully converted to aryl diketones, while α,β-unsaturated amide underwent 1,4-addition followed by C(O)-N bond cleavage to provide diaryl propiophenones. N-Boc amides displayed higher reactivity than Weinreb amides with Grignard reagents. A broad substrate scope, excellent yields, and quick conversion are important features of this methodology.
Sterically controlled iodination of arenes via iridium-catalyzed C-H borylation
Partridge, Benjamin M.,Hartwig, John F.
supporting information, p. 140 - 143 (2013/03/28)
A mild method to prepare aryl and heteroaryl iodides by sequential C-H borylation and iodination is reported. The regioselectivity of this process is controlled by steric effects on the C-H borylation step and is complementary to existing methods to form aryl iodides. The iodination of boronic esters has potential for the synthesis of radiolabeled aryl iodides, as demonstrated by the concise synthesis of a potential tracer for SPECT imaging.

The mononuclear σ-aryl complexes of the type trans -[Pt(σ -C6H4R)(4,7-phen)(PPh3)2] OTf (R=4-CO2SitBuPh2, 4-CONHMe, 3-CO2SitBuPh2, 3-CONHMe; OTf=trifluoromethanesulfonate) containing a monodentate 4,7-phenanthroline (4,7-phen) ligand were prepared by an oxidative addition reaction of an aryl iodide with Pt(PPh3) 4 to yield the key iodoplatinum(II) precursors trans -[PtI(σ-C6H4R)(PPh3) 2], followed by halogen metathesis with one equivalent of 4,7-phen. The reaction of trans -[Pt(σ-C6 H4R)(4,7-phen)(PPh3)2]OTf with labile complexes of the type trans -[Pt(OTf)L2(σ -C6H4R′)] (L=PEt3, R′=H; L=PPh3, R′=4-CO2SitBuPh2 3-CO2SitBuPh2, 3-CONHMe) afforded the asymmetric dinuclear complexes of the type trans -[Pt(σ -C6H4R)L2(μ-4,7-phen)Pt(σ -C6H4R′) L′2](OTf) 2 (L=PPh3, R=4-CO2SitBuPh2, L′=PEt3, R′=H; L=L′=PPh3, R=4-CONHMe, R′ =4-CO2SitBuPh2; R=4-CO2SitBuPh2, R′=3-CONHMe; R=3-CONHMe, R′=3 -CO2SitBuPh2) in which the 4,7-phen acts as a bridging bidentate ligand. The novel dinuclear species undergo an unusual redistribution reaction that is essentially thermoneutral at 298 K. The exchange process involves facile cleavage of a Pt-N bond and the rapid exchange of trans -[PtL2(σ-aryl)] units in the equilibrium mixture.
