consecutive steps: stereoselective construction of allyl anti- and syn-1,2-diols followed by [1,3]-chirality transfer by sigmatropic rearrangement, which allow an access to anti-(2R,3R)- and syn-(2R,3S)-2,3-diaminobutanoic acids. [reaction: see text]
已经开发了基于烯丙基氰酸酯的[3.3]σ重排的经由烯丙基1,2-二醇到邻二胺的立体控制途径。我们的方法包括两个连续的步骤:烯丙基抗-和间-1,2-二醇的立体选择性构建,然后通过σ重排进行[1,3]-手性转移,从而可以获得抗-(2R,3R)-和syn-(2R,3S)-2,3-二氨基丁酸。[反应:看文字]
