In the study of the denitroamination of the (20R)-nitroaminopregnane derivative (1) we found that, in addition to substitution and β-hydrogen elimination products, the arearranged compounds (2) and (4) were formed. Part of this work was supported by the Investigation Programme of the Comisión Asesora de Investigación Científica y Técnica. 2009-10-09T09:38:07Z 2009-10-09T09:38:07Z 1985 artículo http://purl.org/coar/resource_type/c_6501 Journal of Chemical Research(S) 1985: 152-153 (1985) 0308-2350 http://hdl.handle.net/10261/17595 http://dx.doi.org/10.13039/501100007272 en open 2373 bytes 147045 bytes text/plain application/pdf Turpin Distribution |
