Wang, Chunzhang published the artcileA New BINOL-Derived Chiral Bifunctional Phosphine Organocatalyst: Preparation and Application in Asymmetric (Aza)-Morita-Baylis-Hillman Reactions, Synthetic Route of 126613-06-7, the publication is Phosphorus, Sulfur and Silicon and the Related Elements (2013), 188(11), 1548-1554, database is CAplus.
A new BINOL-derived chiral bifunctional phosphine was designed and successfully prepared, which features a cyclic substructure of 1,3,5-diazaphosphinane. This chiral phosphine possesses good air stability in solid state, and it can be conveniently used as an effective nucleophilic phosphine organocatalyst. Preliminary studies showed that it afforded 38% to 99% yields but only modest enantioselectivity (up to 45% ee) in the (aza)-Morita-Baylis-Hillman reactions of activated olefins such as Et acrylate and Me vinyl ketone with aromatic aldehydes or imines.
Phosphorus, Sulfur and Silicon and the Related Elements published new progress about 126613-06-7. 126613-06-7 belongs to esters-buliding-blocks, auxiliary class Chiral Diphenols, name is (R)-[1,1′-Binaphthalene]-2,2′-diyl bis(trifluoromethanesulfonate), and the molecular formula is C10H20N2O6S2, Synthetic Route of 126613-06-7.
