Uses

Used in Pharmaceutical Industry:
1,4-DIBROMO-2,3-BIS(BROMOMETHYL)-2-BUTENE is used as a ubiquitin specific peptidase 9X (USP9X) inhibitor for the treatment of cancer. USP9X is an enzyme that plays a crucial role in the regulation of various cellular processes, including cell growth and division. Inhibiting this enzyme can help disrupt these processes in cancer cells, thereby preventing their uncontrolled proliferation and contributing to the treatment of the disease.

Synthesis and properties of polyethers containing 1,3-butadiene skeleton in the backbone

Polyethers containing 1,3-butadiene skeletons in the backbone were prepared from the polycondensation of 2,3-diiode-methyl-1,3-butadiene (2b) and bisphenols (3). Although the polymerization conditions were limited due to the low reactivity of 2b, a series of polyethers was obtained under the optimized conditions. These polymers exhibited glass transition temperatures (Tgs) around 130 °C, while curing points (Tcures) were observed around 245 °C. In addition, P2b/3a afforded a network polymer by the copolymerization with styrene.

Synthesis of Lignans Based on a Borate-mediated One-pot Sequential Suzuki-Miyaura Coupling of Cyclic Boranes

Lignans are a group of polyphenolic phytochemicals that possess a large spectrum of chemical structures and biological activities. Here the syntheses of lignans – anwulignan, burseran, dehydroxycubebin, ruburisandrin B, and sesamin – are achieved based on a borate-mediated one-pot sequential Suzuki-Miyaura coupling of cis- and trans-fused bicyclic boranes, which were prepared by diastereoselective cyclic hydroboration of exo-cyclic diene with cyclopentyl- and thexylboranes, respectively. A one-pot sequential Suzuki-Miyaura coupling of each cyclic borate with various aryl bromides initiated by activation of the cyclic borane with the carbon nucleophile provided 2,3-dibenzylbutane derivatives with different aromatic substituents. Finally, the syntheses of naturally occurring lignans were accomplished in several steps from the products of Suzuki-Miyaura coupling.
