A short stereoselective formal total synthesis of (+/-)-podophyllotoxin has been carried out from a sulfoxide, using a one-pot tandem conjugate addition/aldol/electrophilic aromatic substitution reaction to form a tetralin, which was converted into picropodophyllin in two steps.
使用一锅串联共轭加成/醛醇/亲电子芳族取代反应从亚砜中进行了(+/-)-鬼臼毒素的短时立体选择性正式全合成,形成了四氢萘,并在两步中将其转化为鬼臼苦素。
