Catalytic Enantioselective Hidrophosphonylation of Aldehydes and Imines
Pedro Merino, Eugenia Marqués-López, Raquel P. Herrera. Catalytic Enantioselective Hidrophosphonylation of Aldehydes and Imines. Adv. Synth. Catal.. 2008, Vol. 350 / 2008, p. 1195-2008.
<p>In this review, recent advances in catalytic asymmetric hydrophosphonylation of aldehydes and imines are discussed. We also summarize several proposed mechanisms for the different possibilities of asymmetric induction and the application of this catalytic methodology to the enantioselective synthesis of a-amino and a-hydroxy phosphonates. A variety of metal-based chiral catalysts as well as several organic catalysts have been exploited as suitable systems for the preparation of enantiomerically pure phosphonates. The recent evolution and future trends of those and other catalytic systems are described.</p>
