Short syntheses of the extremely potent benzopyran prostacyclin mimics 26 and 27 are described using a novel intramolecular Mitsunobu reaction (e.g. 20 → 22) in the key step. This mild cyclization method was also applied to the synthesis of some simple chromans and benzofurans (34 – 38).
在关键步骤中,使用新型分子内Mitsunobu反应(例如20→22)描述了非常有效的苯并吡喃前列环素模拟物26和27的短合成。这种温和的环化方法也适用于一些简单的苯并二氢吡喃和苯并呋喃的合成(34 – 38)。
