chiral bronsted Acid catalyzed enantioselective hydrophosphonylation of imines asymmetric synthesis of α amino phosphonates
Organic Letters, 2005Co-Authors: Takahiko Akiyama, Hisashi Morita, And Junji Itoh, Kohei FuchibeAbstract:A cyclic Phosphoric Acid Derivative, derived from (R)-BINOL, was used as a chiral Bronsted Acid (10 mol %) in hydrophosphonylation of aldimines with diisopropyl phosphite at room temperature. α-Amino phosphonates were obtained with good to high enantioselectivities.

Enantioselective liquid-liquid extraction of (R,S)-phenylglycinol using a bisnaphthyl Phosphoric Acid Derivative as chiral extractant
2011Co-Authors: Schuur Boelo, Verkuijl, Bastiaan J.v., Bokhove Jeroen, Minnaard, Adriaan J., Johannes G. De ,vries, Heeres, Hero J., Feringa, Ben L.Abstract:This study demonstrates that enantioseparation by liquid-liquid extraction can be done in a continuous flow mode on both laboratory and industrial scale and is a promising technique that could become a competitive alternative for crystallization or chromatographic approaches. We studied the enantioselective liquid-liquid extraction of phenylglycinol (Pgl) using a bisnaphthyl Phosphoric Acid extractant. Batch experiments were performed to estimate extraction model parameters. The system was described using an extraction mechanism with homogeneous organic phase complexation. The complexation constants were very large, in the order of 10^8-10^10 L/mol in the temperature range 279
