- Efficient and Practical Synthesis of syn- and anti-b,g- Dihydroxyphosphonates Derived from (S)-Mandelic Acid Haydée Rojas Cabrera Joana Ochoa Morales Emanuel Hernández Núñez Mario Fernández Zertuche Mario Ordóñez Multidisciplinaria (Ciencias Naturales y Exactas) (S) induction mandelic acid ketophosphonates Diastereoselective 1 A new efficient and practical synthesis of syn- and antib,g-dihydroxyphosphonates 1 and 2 was developed in high diastereoselectivityvia reduction of b-ketophosphonates readily obtainedfrom (S)-mandelic acid. An example of diastereoselective 1,2-inductionis showed and a mechanistic model to explain the stereochemicaloutcome is proposed. Assignment of the configuration at the newstereogenic centers was achieved by 1H NMR spectral data of theircorresponding acetonides. 2007 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47551413 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.4 Vol.51
