A new class of bidentate ligands was prepared by a modular approach involving Rh-catalyzed C-H annulation reactions. The resulting conformationally constrained ligands enabled the Pd-catalyzed C-H alkenylation at electron-rich and sterically less hindered positions of electron-rich arenes while promoting the facile oxidation of Pd(0) intermediates by oxygen. This newly introduced ligand class is complementary to the ligands developed for Pd-catalyzed oxidative reactions and may find broad application in transition-metal-catalyzed reactions.

An efficient method for the synthesis of [1,2,4]triazolo-[4,3-a]piperazine derivatives was established based on a gold(I)-catalyzed domino cyclization of an amidrazone substrate with a terminal alkyne. The amidoxime congeners were converted into [1,2,4]oxadiazolo[4,5-a]piperazine derivatives in the presence of a gold catalyst. The oxadiazolopiperazine is a promising scaffold for the design of novel inhibitors against p38 mitogen activated protein kinase (MAP kinase).

Electron-rich arenes are oxidatively photochlorinated in the presence of catalytic amounts of bromide ions, visible light, and 4CzIPN as organic photoredox catalyst. The substrates are brominated in situ in a first photoredox-catalyzed oxidation step, followed by a photocatalyzed ipso-chlorination, yielding the target compounds in high ortho/para regioselectivity. Dioxygen serves as a green and convenient terminal oxidant. The use of aqueous hydrochloric acid as the chloride source reduces the amount of saline by-products.

Annulative pi-extension chemistry provides a concise synthetic route to polycyclic arenes. Herein, we disclose a nondirected annulation approach of unactivated simple arenes. The palladium-catalyzed 2-fold C-H arylation event facilitates tandem C-C linkage relays to furnish fully benzenoid triphenylene frameworks using cyclic diaryliodonium salts. The inseparable regioisomeric mixture of 1- and 2-methyltripheny-lenes is identified by the combined analysis of ion mobility-mass spectrometry, gas-phase infrared spectroscopy, and molecular simulation studies.

A mild one-pot protocol for the synthesis of symmetrical biaryls by sequential Ir-catalyzed C-H borylation and Cu-catalyzed homocoupling of arenes is described. The regiochemistry of the biaryl formed is sterically controlled as dictated by the C-H borylation step. The methodology is also successfully extended to heteroarenes. Some of the products obtained by this approach are impossible to obtain via the Ullmann or the Suzuki coupling protocols. Finally, we have shown a one-pot sequence describing C-H borylation/Cu-catalyzed homocoupling/Pd-catalyzed Suzuki coupling to obtain pi-extended arene frameworks.

Two series of polymethoxychalcones and polymethoxyflavones, including the natural products 2-hydroxy-3,4,5,4,6-pentamethoxychalcone (8c), 5,6,7,8,3,4,5-heptamethoxyflavone (6), 5,7,3,4,5-pentamethoxyflavone (9c), 3-hydroxy-5,6,7,8,3,4,5-heptamethoxyflavone (7), and 3-hydroxy-5,7,3,4,5-pentamethoxyflavone (10), were synthesized. The antiproliferative activity in vitro was evaluated against a panel of three human cancer cell lines (HeLa, HCC1954, and SK-OV-3) by the cell counting kit-8 (CCK-8) assay. The results showed that most of the synthetic compounds exhibited moderate to potent antiproliferative activities. Some compounds displayed equal or higher potential than the positive control drug cisplatin. In particular, compounds 4c, 4e, 8a, and 9a possess IC50 values equal to or below 10 M and are worthy of further investigation.

A highly efficient and regioselective bromination of electron-rich arenes and heteroarenes using commercially available BrCCl3 as a Br source has been developed. The reaction was performed in air under mild conditions with photocatalyst Ru(bpy)(3)Cl-2 center dot 6H(2)O, avoiding the usage of strong acids and strong oxidants. Mono-brominated products were obtained with medium to excellent yields (up to 94%). This strategy has shown good compatibility and high para-selectivity, which will facilitate the complicated synthesis.

Traditional cross-coupling reactions show some disadvantages like the use of organohalides or the production of stoichiometric amounts of waste. The dehydrative homo- or heterocoupling of alcohols therefore arises as an interesting approach for a highly atom-economical formation of carbon-carbon bonds, since water is produced as the only by-product. We herein report a simple and direct, metal-free protocol for the synthesis of olefins by applying catalytic amounts of a sulfonic acid and triphenylphosphane under air. A variety of olefins could be synthesized from benzylic alcohols under relatively mild conditions. Additionally, dehydrative hydroarylation of benzylic alcohols with electron-rich arenes was possible by using only Bronsted acid under otherwise same reaction conditions. We could show that phosphane additives are essential to overcome oligomerization as main side reaction by the occupancy of the reactive carbocation intermediate.
