Abstract: Abstract The synthesis of an unsymmetrical silyl-ether-modified 1-oxazolinyl 1,2′-bis(diphenylphosphine) ferrocene is proposed herein. The designed 1,2′-bisphosphine is generated from 1-bromo-l’-carboxyferrocene in six synthetic steps in moderate yield with high diastereoselectivity. Moreover, a 2,5-bisphosphine analog is… read more here.

DOI: 10.1055/s-0043-1775038
Abstract: The enantioselective desymmetrization of 2,2-disubstituted cyclohexane-1,3-diones has been realized through an unprecedented chiral-bisphosphine-catalyzed asymmetric Staudinger/aza-Wittig reaction. The key to this work’s success lies in utilizing an electronically rich and sterically hindered chiral bisphosphine reagent, namely… read more here.
