The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine(SMILESS: N1(P2OC3=CC=C4C=CC=CC4=C3C5=C6C=CC=CC6=CC=C5O2)C7=CC=CC=C7C=CC8=CC=CC=C81,cas:1265884-98-7) is researched.Name: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole. The article 《Total Synthesis of Taiwaniadducts B, C, and D》 in relation to this compound, is published in Journal of the American Chemical Society. Let’s take a look at the latest research on 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
This literature about this compound(1265884-98-7)Synthetic Route of C34H22NO2Phas given us a lot of inspiration, and I hope that the research on this compound(5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine) can be further advanced. Maybe we can get more compounds in a similar way.
