A total synthesis of the novel neurotrophic agent (+)-lactacystin (1) has been achieved in 11 steps and 14% overall yield from (2R,3S)-3-hydroxyleucine [(+)-16]. The construction and bioassay of several active analogs are also described. A new asymmetric approach furnished the four stereoisomers of 3-hydroxyleucine, as required starting materials in high overall yield and enantiomeric purity.
新型神经营养剂 (+)-lactacystin (1) 的全合成已在 11 个步骤中实现,从 (2R,3S)-3-羟基亮氨酸 [(+)-16] 的总产率为 14%。还描述了几种活性类似物的构建和生物测定。一种新的不对称方法提供了 3-羟基亮氨酸的四种立体异构体,作为高总产率和对映体纯度所需的起始材料。
