Yang, Fan published the artcilePalladium/Lewis Acid Co-catalyzed Divergent Asymmetric Ring-Opening Reactions of Azabenzonorbornadienes with Alcohols, Name: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole, the publication is Organic Letters (2016), 18(19), 4832-4835, database is CAplus and MEDLINE.

By fine tuning the combinations of chiral palladium catalysts and Lewis acids, both the addnl. and reductive asym. ring-opening reactions of azabenzonorbornadienes with alcs. were accomplished with good chemoselectivity, regioselectivity, and enantioselectivity. It was proven that the reductive ring-opening products were generated through a transfer hydrogenation process with alcs. as hydrogen source.
