The first totalsynthesis of the abietaquinone methide diterpenoid (−)-3-oxoisotaxodione is reported. The key enabling step is the use of a chiral bicyclic hydrazide as an organocatalyst for the enantioselective polyene cyclization of a (Z)-polyene substrate to form the cis-decalin core of the natural product. The α-oxo-para-quinone methide unit is formed by a two-step oxidation from a phenol, enabling
报道了松香醌甲基二萜类 (-)-3-氧代异紫杉二酮的首次全合成。关键的实现步骤是使用手性双环酰肼作为有机催化剂,用于 ( Z )-多烯底物的对映选择性多烯环化以形成天然产物的顺式-萘烷核心。α-氧代-对-醌甲基化物单元由苯酚通过两步氧化形成,从而能够有效合成天然产物。
