functionality into alkyl group at the ortho position of N heteroaromatic rings. We have reported the first example of asymmetric Boekelheide rearrangement applied to a set of 2-alkyl-pyridine N-oxide derivatives using (R) Mosher’s acyl chloride as activator of the rearrangement to give, after hydrolysis, enantiomerically enriched 1-(2-pyridinyl)alkyl alcohol. Diastereoselectivity of the process was studied at
用酰化剂处理2-烷基
吡啶N-氧化物代表了将氧官能团引入到N个杂芳族环的邻位的烷基中的既定程序。我们已经报道了使用(R)Mosher酰

水解后得到对映体富集的1-(2-
吡啶基)烷基醇。在低温下在不同溶剂中研究了该方法的非对映选择性,并得到了初步计算机模拟的支持。
