Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Zhang, Jinxia, once mentioned the application of 18437-78-0, Name is Tris(4-fluorophenyl)phosphine, molecular formula is C18H12F3P, molecular weight is 316.26, MDL number is MFCD00013553, category is chiral-phosphine-ligands. Now introduce a scientific discovery about this category, Recommanded Product: Tris(4-fluorophenyl)phosphine.
Chiral zinc amidate catalyzed additions of diethylzinc to aldehydes
A series of bifunctional Spiro ligands bearing carboxamide-phosphine oxide groups and ethylzinc carboxamidates from these ligands as catalysts for Et2Zn additions to aldehydes were reported. Excellent yields were obtained with moderate ee’s in Et2Zn additions to benzaldehyde derivatives, implying effectiveness of our newly designed catalytic structures as well as mediocre stereocontrol by these chiral ligands. Possible transition states were suggested based on the crystal structures of two ligands. (C) 2019 Elsevier Ltd. All rights reserved.
