So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Deng, Jun; Zhou, Shupeng; Zhang, Wenhao; Li, Jian; Li, Ruofan; Li, Ang researched the compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine( cas:1265884-98-7 ).Recommanded Product: 1265884-98-7.They published the article 《Total Synthesis of Taiwaniadducts B, C, and D》 about this compound( cas:1265884-98-7 ) in Journal of the American Chemical Society. Keywords: enantioselective synthesis taiwaniadduct B C D; iridium catalyzed asym polyene cyclization taiwaniadduct synthesis; erbium catalyzed Diels Alder taiwaniadduct synthesis; carbonyl ene cyclization taiwaniadduct synthesis. We’ll tell you more about this compound (cas:1265884-98-7).
The first total syntheses of taiwaniadducts B, C, and D have been accomplished. Two diterpenoid segments [trans-ozic Me ester (I) and II] were prepared with high enantiopurity, both through Ir-catalyzed asym. polyene cyclization. A sterically demanding I + II intermol. Diels-Alder reaction promoted by Er(fod)3 assembled the scaffold of taiwaniadducts B and C. A carbonyl-ene cyclization forged the cage motif of taiwaniadduct D at a late stage, providing over 200 mg of this compound
