(2S,3S)-(+)-Thiomicamine 3, a commercially available aminodiol, was transformed into (4R,5S)-5-bydroxymethyl-4-(p-methylthiopbenyl)-2-oxazolidinone 10, a compound related to cytoxazone-type biologically active natural products. The synthetic strategy of the highly regio- and stereoselective synthesis was based upon the reversal of the position of the hydroxyl and amine functionalities in 3, accomplished via azidolysis of the key intermediate, epoxide 6.

(2S,3S)-(+)-Thiomicamine 3(一种市场上可获得的氨基二醇)被转化为(4R,5S)-5-羟甲基-4-(对甲硫基苯基)-2-氧杂环戊酮 10,这是一种与生物活性天然产物细胞松素类(cytoxazone-type)相关的化合物。这种高度区域选择性和立体选择性的合成策略基于对3中羟基和胺基功能团位置的反转,这一转变是通过关键中间体(环氧化物 6)的叠氮化物分解完成的。© 2006 Elsevier Ltd. 保留所有权利。
