total synthesis of a series of botryanes, which are an important group of sesquiterpene antibiotics isolated from the metabolites of the fungus Botrytis cinerea, has been reported. The highly functionalized hydrindane skeleton of the botryanes was efficiently synthesized via an unusual intramolecular Diels-Alder reaction, which was promoted by TsOH as a protic acid. The concise total synthesis of (±)-hypocrolide
已经报道了一系列硼烷的集体全合成,所述硼烷是从灰葡萄孢菌的代谢物中分离出的重要的倍半萜类抗生素。通过不寻常的分子内Diels-Alder反应有效地合成了硼烷的高度官能化的氢化茚骨架,该反应由TsOH作为质子酸促进。从容易获得的起始原料开始,只需8个步骤即可完成具有挑战性的六环骨架的(±)-次大环内酯A的简明全合成。
