maleic anhydride yielded the 1,2,3-trisubstituted tetrahydronaphthalene (8) with a cis configuration, via the benzyl equivalent of the Peterson reaction, which was converted stereoselectively into (±)-deoxypodophyllotoxin (13) in good overall yield via a regio- and stereo-selective sequence of reactions.
用过量的马来酸酐对邻羟基甲基苄基硅烷(3)进行热处理,通过彼得森反应的苄基当量,生成具有顺式构型的1,2,3-三取代四氢萘(8),该立体异构体被立体选择性地转化为(± )-脱氧鬼臼毒素(13)通过区域和立体选择反应序列具有良好的总收率。
