Fecha de publicación: | 9-dic-2005 | Editor: | American Chemical Society | Citación: | Organic Letters 8(1): 127-130 (2006) | Resumen: | Expanding the scope of enantioselective catalysis via DKR, transfer hydrogenation of a variety of cyclic alpha-halo ketones was accomplished using the Noyori/Ikariya (R,R)- or (S,S)-I catalysts and either HCO(2)H/Et(3)N or HCO(2)Na/n-Bu(4)NBr in H(2)O/CH(2)Cl(2) as the hydrogen sources. Good yields of vicinal bromo-, chloro-, and fluorohydrins with excellent de and ee levels were achieved in most cases after a simple tuning of reaction conditions. | Descripción: | 4 páginas, 1 figura, 1 tabla, 3 esquemas. | Versión del editor: | http://dx.doi.org/10.1021/ol052821k | URI: | http://hdl.handle.net/10261/37646 | DOI: | 10.1021/ol052821k | ISSN: | 1523-7060 |
