Toscano Multidisciplinaria (Ciencias Naturales y Exactas) 17 amino estrogen Pentolame ray analysis The molecular and crystal structure of Pentolame, a 17β-aminoestrogen (17β-(5-hydroxy-1-pentylamino)-1,3,5(10)-estratrien-3-ol), has been determined by single crystal X-ray diffraction asits monohydrate. The structure was used to determine the absoluteconfiguration of the newly formed stereogenic centre (C17), whichcould not be established unambiguously by NMR spectroscopy. Thisstudy confirms the absolute configuration as 17S by internal referencewith the starting material, estrone [(8R,9S,13S,14S)-3-Hydroxyestra-1,3,5(10)-trien-17-one]. Pentolame monohydrate crystallizes in thetriclinic system, space group P 1 with Z = 1. The B ring adopts thetypical conformation of a distorted 7α,8β-half-chair. In crystalpacking, the water molecule plays an essential role joining adjacentinfinite chains, made up by head to tail hydrogen bonded steroidmolecules. 2004 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47548409 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.48 |
