Some new chemistry of the chiral nitronic acid and nitronic esters is described. Conversions with retention of configuration are found among the chiral nitronic acid, oxime, nitronic esters and O-alkyloximes. α,β-Elimination reactions of nitronic esters are observed for the first time. Novel and enantiopure chiral bisheterocyclic compounds are obtained via highly diastereoselective 1,3-dipolar cycloaddition
描述了手性硝酸和硝酸酯的一些新化学。在手性硝酸,肟,硝酸酯和O-烷基肟中发现具有构型保留的转化。首次观察到亚硝酸酯的α,β-消除反应。通过手性氮酸酯与丙烯酸乙酯的高度非对映选择性的1,3-偶极环加成反应,可以得到新的和对映体纯的手性双环化合物。
