Biphenyl-based diaminophosphine oxides as air-stable preligands for the nickel-catalyzed kumada-tamao-corriu coupling of deactivated aryl chlorides, fluorides, and tosylates

A cooperative couple: Cooperative bimetallic activation of C-F and C-O bonds gave rise to easy coupling with aryl fluorides and tosylates. Novel air- and moisture-stable diaminophosphine oxides derived from 1,1?-biphenyl-2, 2?-diamine proved to be versatile preligands for the nickel-catalyzed cross-coupling of aryl Grignard reagents with a variety of deactivated aryl chlorides, fluorides, and tosylates (see scheme).

Discovery of the cancer cell selective dual acting anti-cancer agent (Z)-2-(1H-indol-3-yl)-3-(isoquinolin-5-yl)acrylonitrile (A131)

Selective targeting of cancer cells over normal cells is a key objective of targeted therapy. However few approaches achieve true mechanistic selectivity resulting in debilitating side effects and dose limitation. In this work we describe the discovery of A131 (4a), a new agent with an unprecedented dual mechanism of action targeting both mitosis and autophagy. Compound 4a was first identified in a phenotypic screen in which HeLa cells treated with 4a manifested mitotic arrest along with formation of multiple vesicles. Further investigations showed that 4a causes an increase in mitotic marker pH3 and autophagy marker LC3. Importantly 4a induces cell death in cancer cells while sparing normal cells which regrow after 4a is removed. Dual activities against pH3 and LC3 markers are required for cancer cell selectivity. An extensive SAR investigation confirmed 4a as the optimal dual inhibitor with potency against a panel of 30 cancer cell lines (average antiproliferative GI50 1.5 muM). In a mouse model of paclitaxel-resistant colon cancer, 4a showed 74% tumor growth inhibition when administered at a dose of 20 mg/kg IP twice a day.

Synthesis of conjugated tri(hetero)aryl derivatives based on one-pot double Suzuki-miyaura couplings using bifunctional dipotassium phenylene-1,4- bis(trifluoroborate)

An efficient one-pot double Suzuki-Miyaura cross–coupling reaction between bifunctional phenylene-1,4-bis(potassium trifluoroborate) and aryl and heteroaryl bromides is described. The scope and limitations of this methodology that enables the synthesis of tri(hetero)aryl derivatives, potentially useful as drugs and in the field of materials science, have also been probed.

Transition-metal-free access to primary anilines from boronic acids and a common +NH2 equivalent

Diversely substituted anilines are prepared by treatment of functionalized arylboronic acids with a common, inexpensive source of electrophilic nitrogen (H2N-OSO3H, HSA) under basic aqueous conditions. Electron-rich substrates are found to be the most reactive by this method. However, even moderately electron-poor substrates are well tolerated under the room temperature conditions. Sterically hindered substrates appear to be equally effective compared to unhindered ones. Highly electron-deficient substrates afford product in very low yields at room temperature, but moderate to good yields are obtained at refluxing temperatures. Our method is also amenable to electrophilic amination of several common boronic acid derivatives (e.g., pinacol esters). We demonstrate that it can be combined with metal-halogen exchange reactions or a variety of directed ortho metalation protocols in a “one-pot” sequence for the synthesis of aromatic amines with unique substitution patterns. DFT studies, in combination with experimental results, suggest that the reaction occurs via base-mediated activation of HSA, followed by 1,2 aryl B-N migration. This mode of activation appears to be critical for the success of the reaction and allows, for the first time, a general, electrophilic amination of boronic acids at ambient temperature.
