- Synthesis and Absolute Configuration of (20R)-20-Acetyl-23,24- bisnorcholanic Lactones Prepared from (E)-(20S,25R)- and (E)-(20S,25S)- 20,23-Diacetylfurost-22-enes Víctor Gómez Calvario Guadalupe Hernández Linares Socorro Meza Reyes Sara Montiel Smith Jesús Sandoval Ramírez Sylvain Bernès Multidisciplinaria (Ciencias Naturales y Exactas) 23 24 20 22 enes The synthesis of (20R)-20-acetyl-23,24-bisnorcholaniclactones from (E)-(20S,25R)- and (E)-(20S,25R)-20,23-diacetylfurost-22-enes (derived from diosgenin, hecogenin and sarsasapogenin)is reported. The configuration of the stereogenic center at C-20 wasdetermined by NMR and single crystal X-ray diffraction studies. Thelactones can be used in the synthesis of a variety of steroidal derivatives. 2007 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47551409 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
