He, Cheng-Yu; Li, Qing-Hua; Wang, Xin; Wang, Feng; Tian, Ping; Lin, Guo-Qiang published the article 《Copper-Catalyzed Asymmetric Borylative Cyclization of Cyclohexadienone-Containing 1,6-Dienes》. Keywords: copper catalyzed asym borylative cyclization cyclohexadienone diene; borylated tetrahydrobenzofuranone preparation; crystal structure borylated tetrahydrobenzofuranone; mol structure borylated tetrahydrobenzofuranone.They researched the compound: (((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine)( cas:32305-98-9 ).Application In Synthesis of (((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine). Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:32305-98-9) here.
Due to the low reactivity of 1,6-dienes and the challenge of selectively differentiating such two olefins, the development of metal-catalyzed asym. cyclization of 1,6-dienes remains largely underdeveloped. Herein, the authors describe the 1st Cu(I)-catalyzed asym. borylative cyclization of cyclohexadienone-tethered terminal alkenes (1,6-dienes) via a tandem process: the regioselective borocupration of the electron-rich terminal alkene and subsequent conjugate addition of stereospecific secondary alkyl-Cu(I) to the electron-deficient cyclohexadienone, affording enantioenriched bicyclic skeletons bearing three contiguous stereocenters in all cis-form. Meanwhile, this mild catalytic protocol is generally compatible with a wide range of functional groups, which allows further facile conversion of the cyclization products.
