A novel method to obtain racemic 1-nitroalkan-2-ols by reaction of bromonitromethane with a variety of aldehydes and promoted by SmI2 is reported. On the basis of these results, the chiral version has also been performed with chiral N,N-dibenzyl amino aldehydes, affording the corresponding enantiopure 3-amino-1-nitroalkan-2-ols with good stereoselectivity.
报道了一种通过
溴硝基甲烷与各种醛反应并由SmI 2促进而获得外消旋1-硝基烷-2-醇的新方法。基于这些结果,也已经用手性N,N-二苄基
氨基醛进行了手性反应,从而提供了具有良好立体选择性的相应的对映体纯的3-
氨基-1-硝基烷-2-醇。
