4R)-3-amino-2-hydroxymethyl-4-hydroxypyrrolidine 5 has been produced in an efficient synthesis from trans-4-hydroxy-l-proline 8. The key step involves a tethered aminohydroxylation of the alkene 7 to introduce regio- and stereoselectively the amino alcohol functionality in the resulting products 6 and 13. Subsequent deprotection steps furnish the target molecule 5 as well as several differentially protected analogues
新型(2 S,3 S,4 R)-3-氨基-2-羟基甲基-4-羟基吡咯烷5已由反式-4-羟基-1-脯氨酸8高效合成。关键步骤涉及链烯7的束缚氨基羟基化,以在形成的产物6和13中区域和立体选择性地引入氨基醇官能团。随后的脱保护步骤提供了靶分子5以及几种不同保护的类似物。
