Grignard reaction, Mitsunobu stereoinversion, ethyl diazoacetate addition, and selective reduction of the ketone is employed as a key step for the total synthesis of (+)-cardiobutanolide described; a similar strategy is also reported for the first total synthesis of (+)-3-epi-cardiobutanolide.
采用格氏试剂,Mitsunobu立体转化,重氮乙酸乙酯加成和酮的选择性还原,从3 - O-苄基-1,2- O-异亚丙基-α-d-二甲苯基-戊二醛-1,4-呋喃糖开始的Chiron方法将其用作所述(+)-心脏丁醇化物的全合成的关键步骤;对于(+)-3-表位-心脏丁醇化物的第一个全合成,也报道了类似的策略。
