2016-11-3 · organoboron reagents to phosphinoylimines20, tert-butoxycarbonyl (Boc) imines21 or isatins20. A protonated amine within the catalyst’s structure is key to high efficiency and enantioselectivity20,asit allows substrates with a second Lewis basic site to react with high stereoselectivity (other than an interaction with the catalyst’s boron ...
