A stereoselective synthesis of the (+)-decarestrictine L has been described following our own developed iodine-catalyzed tandem isomerization followed by C–O and C–C bond formation reaction for the construction of trans-2,6-disubstituted dihydropyran as the key step. Other important reactions used for this synthesis are 5-exo-trig-iodolactonization, Mitsunobu inversion, and Wacker’s oxidation. The
在我们自己开发的碘催化的串联异构化反应之后,通过C–O和CC键形成反应以构建反式-2,6-二取代的二氢吡喃为关键,已经描述了(+)-去卡地汀L的立体选择性合成步。用于该合成的其他重要反应是5 -exo- trig-碘代磺化,Mitsunobu转化和Wacker氧化。目标分子的总合成以10个线性步骤完成,总产率为28%。
