A general method has been developed for the stereoselective construction of 2,6-disubstituted dihydropyrans based on the Lewis acid-catalyzed intramolecular reactions of oxocarbenium ions with vinylstannanes. This novel methodology was applied to the enantioselective total synthesis of (−)-centrolobine.
已经开发了一种基于路易斯碳催化氧碳鎓离子与乙烯基stananes的分子内反应来立体选择性地构建2,6-二取代的二氢吡喃的一般方法。这种新颖的方法应用于(-)-centrolobine的对映选择性全合成。
