I2/TBHP mediated multiple C[sbnd]H bonds functionalization of azaarenes with methylarenes to synthesize iodoisoquinolinones via iodination/N-benzylation/amidation sequence

An oxidative multi-functionalization of azaarenes with benzylic C[sbnd]H bonds of methylarenes via iodination/N-benzylation/amidation cascade, to produce N-benzyl-4-iodoisoquinolin-1(2H)-ones and N-benzyl-3-iodoquinolin-2(1H)-ones is developed. The molecular iodine plays a triple role in activating benzylic sp3 C[sbnd]H bond of methylbenzenes, accelerating the oxidation process and serving as iodination reagent. This reaction utilizes cheap and readily available azaarenes and methylarenes as starting materials and proceeds under metal-free conditions to construct C-I, C[sbnd]N and C[dbnd]O bonds consecutively and afford iodo(iso)quinolinones efficiently.

A preparative route to methyl 3-(heteroaryl)acrylates using Heck methodology

Methyl 3-(heteroaryl)acrylates were prepared using Heck coupling of heteroarene halides with methyl acrylate mediated by Pd(OAc)2/ P(OCH3)3. Reactions were highly efficient (reaction times between 60 and 120 min) and scalable to 100 g of heteroarene halide. The isolated yields are from 76 to 99%.

Direct 2-arylation of thiophene using low loading of a phosphine-free palladium catalyst

The direct coupling of aryl halides with thiophene would be a considerable advantage for sustainable development because of only HBr associated with a base as by-product is formed and the number of steps to prepare these compounds is less than in more classical coupling reactions. We observed that through the use of only 0.2mol% Pd(OAc)2 as the catalyst, a range of aryl bromides undergoes coupling via a C-H bond activation/functionalization reaction with thiophene to give 2-arylated thiophenes in good yields. In most cases, only traces of polyarylated thiophenes were detected when a large excess of thiophene was employed. This air-stable catalyst can be used with a wide variety of aryl bromides.

Pd-catalyzed carbonylative alpha-arylation of aryl bromides: Scope and mechanistic studies

Reaction conditions for the three-component synthesis of aryl 1,3-diketones are reported applying the palladium-catalyzed carbonylative alpha-arylation of ketones with aryl bromides. The optimal conditions were found by using a catalytic system derived from [Pd(dba)2] (dba=dibenzylideneacetone) as the palladium source and 1,3-bis(diphenylphosphino)propane (DPPP) as the bidentate ligand. These transformations were run in the two-chamber reactor, COware, applying only 1.5 equivalents of carbon monoxide generated from the CO-releasing compound, 9-methylfluorene-9-carbonyl chloride (COgen). The methodology proved adaptable to a wide variety of aryl and heteroaryl bromides leading to a diverse range of aryl 1,3-diketones. A mechanistic investigation of this transformation relying on 31P and 13C NMR spectroscopy was undertaken to determine the possible catalytic pathway. Our results revealed that the combination of [Pd(dba)2] and DPPP was only reactive towards 4-bromoanisole in the presence of the sodium enolate of propiophenone suggesting that a [Pd(dppp)(enolate)] anion was initially generated before the oxidative-addition step. Subsequent CO insertion into an [Pd(Ar)(dppp)(enolate)] species provided the 1,3-diketone. These results indicate that a catalytic cycle, different from the classical carbonylation mechanism proposed by Heck, is operating. To investigate the effect of the dba ligand, the Pd0 precursor, [Pd(eta3-1-PhC 3H4)(eta5-C5H5)], was examined. In the presence of DPPP, and in contrast to [Pd(dba)2], its oxidative addition with 4-bromoanisole occurred smoothly providing the [PdBr(Ar)(dppp)] complex. After treatment with CO, the acyl complex [Pd(CO)Br(Ar)(dppp)] was generated, however, its treatment with the sodium enolate led exclusively to the acylated enol in high yield. Nevertheless, the carbonylative alpha-arylation of 4-bromoanisole with either catalytic or stoichiometric [Pd(eta3-1-PhC3H4) (eta5-C5H5)] over a short reaction time, led to the 1,3-diketone product. Because none of the acylated enol was detected, this implied that a similar mechanistic pathway is operating as that observed for the same transformation with [Pd(dba)2] as the Pd source. CO-operation is the key! The first palladium-catalyzed carbonylative alpha-arylation of aryl bromides is described. A wide array of different aryl 1,3-diketones can be isolated in good-to-excellent yields using only stoichiometric amounts of CO (see scheme). A mechanistic study is presented that suggests the need for enolate coordination prior to oxidative addition when [Pd(dba)2] is employed as the precatalyst. Copyright

Structure-Based Design of an in Vivo Active Selective BRD9 Inhibitor

Components of the chromatin remodelling switch/sucrose nonfermentable (SWI/SNF) complex are recurrently mutated in tumors, suggesting that altering the activity of the complex plays a role in oncogenesis. However, the role that the individual subunits play in this process is not clear. We set out to develop an inhibitor compound targeting the bromodomain of BRD9 in order to evaluate its function within the SWI/SNF complex. Here, we present the discovery and development of a potent and selective BRD9 bromodomain inhibitor series based on a new pyridinone-like scaffold. Crystallographic information on the inhibitors bound to BRD9 guided their development with respect to potency for BRD9 and selectivity against BRD4. These compounds modulate BRD9 bromodomain cellular function and display antitumor activity in an AML xenograft model. Two chemical probes, BI-7273 (1) and BI-9564 (2), were identified that should prove to be useful in further exploring BRD9 bromodomain biology in both in vitro and in vivo settings.
