Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Organic Letters called Rhodium-Catalyzed Asymmetric Arylative Ring-Opening Reactions of Heterobicyclic Alkenes with Anilines, Author is Chen, Jingchao; Zou, Lingling; Zeng, Chaoyuan; Zhou, Yongyun; Fan, Baomin, which mentions a compound: 503538-69-0, SMILESS is FC1(F)OC2=CC=C(P(C3=CC=CC=C3)C4=CC=CC=C4)C(C5=C6OC(F)(F)OC6=CC=C5P(C7=CC=CC=C7)C8=CC=CC=C8)=C2O1, Molecular C38H24F4O4P2, Related Products of 503538-69-0.
Asym. arylative ring-opening reactions of heterobicyclic alkenes with anilines have been reported for the first time. A wide range of heterobicyclic alkenes, including azabenzonorbornadienes and oxabenzonorbornadienes, were well tolerated in the reaction with various anilines, and they generally delivered the corresponding chiral aryltetralin derivatives I [R1 = H, 6,7-di-Br, 6,7-di-Me, 5,8-di-OMe etc., R2 = H, o-Me m-OMe, p-OMe etc., R3 = R4 = Me, Et, X = NBoc, O, NTs, NCbz etc.] in good to excellent enantioselectivities. The reaction is speculated to proceed through the Friedel-Crafts reaction pathway.
