Abstract We describe a concise and straightforward approach to the total syntheses of (+)-Strictifolione and Cryptofolione in the longest linear sequences of four steps and six steps from 3-phenyl propanal and trans-cinnamaldehyde, respectively. The route utilized a titanium tetraisopropoxide/(R)-[1,1'-binaphthalene]-2,2'-diol catalyzed Mukaiyama aldol reaction, indium(0)-promoted Barbier reaction
摘要 我们描述了一种简明直接的方法,分别从 3-苯基丙醛和反式肉桂醛以最长的四步和六步线性序列全合成 (+)-Strictifolione 和 Cryptofolione。该路线利用四异丙氧基钛/(R)-[1,1'-联萘]-2,2'-二醇催化的Mukaiyama羟醛反应、铟(0)-促进的Barbier反应和烯烃交叉复分解作为关键反应。图形概要
