Usage

General Description

Benzylmagnesium bromide is an organometallic compound that consists of a benzyl group attached to a magnesium atom with a bromine atom as a counterion. It is commonly used as a strong nucleophile in organic synthesis reactions, particularly in Grignard reactions, where it can be used to form carbon-carbon bonds with a wide variety of electrophiles. Benzylmagnesium bromide is a versatile reagent that is utilized in the formation of a range of compounds, including alcohols, ketones, and esters. Its ability to selectively react with specific functional groups makes it a valuable tool for chemists in the development of new molecules and materials. However, it is also highly reactive and must be handled with care due to its sensitivity to air and moisture.

Discovery of 2,4-diaminopyrimidine derivatives targeting p21-activated kinase 4: Biological evaluation and docking studies

In this study, novel 2,4-diaminopyrimidine derivatives targeting p21-activated kinase 4 (PAK4) were discovered and evaluated for their biological activity against PAK4. Among the derivatives studied, promising compounds A2, B6, and B8 displayed the highest inhibitory activities against PAK4 (IC50 = 18.4, 5.9, and 20.4 nM, respectively). From the cellular assay, compound B6 exhibited the highest potency with an IC50 value of 2.533 μM against A549 cells. Some compounds were selected for computational ADME (absorption, distribution, metabolism, and elimination) properties and molecular docking studies against PAK4. The detailed structure–activity relationship based on the biochemical activities and molecular docking studies were explored. According to the docking studies, compound B6 had the lowest docking score (docking energy: ?7.593 kcal/mol). The molecular docking simulation indicated the binding mode between compound B6 and PAK4. All these results suggest compound B6 as a useful candidate for the development of a PAK4 inhibitor.

Iron-Catalyzed Cross-Coupling of Alkynyl and Styrenyl Chlorides with Alkyl Grignard Reagents in Batch and Flow

Transition-metal-catalyzed cross-coupling chemistry can be regarded as one of the most powerful protocols to construct carbon–carbon bonds. While the field is still dominated by palladium catalysis, there is an increasing interest to develop protocols that utilize cheaper and more sustainable metal sources. Herein, we report a selective, practical, and fast iron-based cross-coupling reaction that enables the formation of Csp?Csp3 and Csp2?Csp3 bonds. In a telescoped flow process, the reaction can be combined with the Grignard reagent synthesis. Moreover, flow allows the use of a supporting ligand to be avoided without eroding the reaction selectivity.

Syntheses of arabinose-derived pyrrolidine catalysts and their applications in intramolecular Diels-Alder reactions

Six chiral hydroxylated pyrrolidine catalysts were synthesized from commercially available D-arabinose in seven steps. Various aromatic substituents α to the amine can be introduced readily by a Grignard reaction, which enables facile optimization of the catalyst performance. The stereoselectivities of these catalysts have been assessed by comparing with those of MacMillan's imidazolidinone in a known intramolecular Diels-Alder (IMDA) reaction of a triene. Two additional IMDA reactions of symmetrical dienals with concomitant desymmetrisation further established the potential use of these novel amine catalysts. These pyrrolidines are valuable catalysts for other synthetic transformations.
