synthesis of all the possible stereoisomers of acaterin 1, naturally occurring ACAT inhibitor with acetogenin-type skeleton, was accomplished starting from both the enantiomers of ethyl 3-hydroxy butanoate 3. Stereochemistry of synthetic samples 1 and pseudo-1 was unambiguously assigned by converting to the authentic compound. The absolute configuration of natural acaterin was determined as (4R, 1′R) by careful
的acaterin所有可能的立体异构体的对映选择性合成1,天然存在的与荔枝内酯型骨架ACAT抑制剂,在实现了从3-羟基丁酸的两个对映异构体起始3。通过转换为真实化合物,可以明确分配合成样品1和假1的立体化学。天然acaterin的绝对构型确定为(4 - [R,1' - [R ),通过TLC行为和光谱和光学数据仔细比较。
