  • Synthesis of 7-substituted-5-androstene derivatives promoted by SmI2
    作者:Qin Gu、Yun-Hong Zheng、Yuan-Chao Li
    DOI:10.1016/j.steroids.2005.08.008
    日期:2006.2
    The 7-substituted-5-androstene derivatives 2a-10a and 2b-10b were prepared by reaction of 3 beta,17 beta-di(tert-butyldimethylsilyloxy)-5-androsten-7-one 1 with different organic halides. The resulting 7 alpha- and 7 beta-isomers were carefully separated by column chromatography The structural assignments of the 7 alpha- and 7 beta-isorners were determined by C-13-NMR.

  • Novel Stereoselective Synthesis of 7β-Methyl-Substituted 5-Androstene Derivatives
    作者:Yunhong Zheng、Yuanchao Li
    DOI:10.1021/jo020290x
    日期:2003.2.1
    The 7beta-methyl-5-androstene derivatives 11a-c were prepared in good yield with high stereoselectivities starting from 3beta-acetoxyandrost-5-en-17-one 4. The addition of methylmagnesium iodide to the 7-carbonyl group of 7a-c gave, after hydrolysis, two isomers 9a-c and 10a-c, which were stereoselectively deoxygenated by means of an ionic hydrogenation to afford the compounds 11a-c.
    从3β-乙酰氧基-雄烷-5-en-17-one 4开始,以高收率和高立体选择性制备7β-甲基-5-雄烯衍生物11a-c。将甲基碘化镁加到7a-c的7-羰基上在水解后,得到两个异构体9a-c和10a-c,它们通过离子氢化被立体选择性地脱氧,得到化合物11a-c。
