Starting from (R)-citronellic acid and (R)-seudenol, the total synthesis of (+)-aplykurodinone-1, a highly degraded marine steroid, has been achieved in 11 steps and in 19% overall yield with excellent stereochemical control. In addition to the features such as an Ireland–Claisen rearrangement, an intramolecular carbonyl–ene cyclization, and an intramolecular Michael addition, the present synthetic
从(R)香柠檬酸和(R)-seudenol开始,已高度分解立体海洋甾族化合物(+)-aplykurodinone-1的总合成过程已达到11个步骤,总收率达到19%,并具有出色的立体化学控制能力。除了具有爱尔兰-克莱森重排,分子内羰基-烯环化和分子内迈克尔加成等功能外,无需使用保护基即可完成本合成策略。
