Avenues to bi- and tricyclic building blocks for the elaboration of sordaricin and its analogues are described. The target molecules were obtained through inter- and intramolecular Diels-Alder reactions of a number of previously unknown cyclopentadienes. Unusual properties of 3-cyanoenones and 1-cyanocyclopentadienes have been unveiled and circumvented.
描述了用于合成索德菌素及其类似物的双环和三环结构单元的构建途径。目标分子是通过一些此前未知的环戊二烯的分子间和分子内狄尔斯-阿尔德反应获得的。已揭示并克服了3-氰基烯酮和1-氰基环戊二烯的异常性质。
