Description
This chiral dioxaphosphepine amine features a rigid, electron-rich scaffold with two stereogenic centers, enabling high enantioselectivity in asymmetric catalysis. The bis(1-phenylethyl) substituents provide steric bulk and enhance solubility in organic media, while the dinaphtho-fused ring system ensures thermal stability and resistance to oxidation under standard bench conditions.
Application
(11bS)-N,N-Bis[(S)-1-phenylethyl]-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine serves as a chiral, sterically encumbered phosphine ligand that enables selective cross-coupling reactions in palladium-catalyzed transformations. Its rigid dinaphtho scaffold enhances thermal stability and oxidative resistance, while the bis(1-phenylethyl) substitution provides high enantiocontrol in asymmetric synthesis. The ligand facilitates efficient coupling of aryl halides and pseudohalides under mild conditions, offering excellent functional group tolerance and ease of purification—ideal for iterative synthesis of complex pharmaceutical intermediates.
