The present invention is a method for synthesizing furanosteroids. The method involves intramolecular Diels-Alder/retro-Diels-Alder reaction and tautomerization of a functionalized alkyne oxazole to produce a furo[2,3-b]phenol derivative which is elaborated by intermolecular and intramolecular condensations to generate ring-A of the furanosteroid. Furanosteroids and pharmaceutical compositions containing the same are also provided.
本发明涉及一种合成呋喃甾体的方法。该方法涉及分子内Diels-Alder/retro-Diels-Alder反应和一个官能化炔基噁唑的异构化,以产生一种furo[2,3-b]苯酚衍生物,通过分子间和分子内缩合反应来生成呋喃甾体的A环。同时还提供了呋喃甾体和含有其的药物组合物。
