Abstract

... Intramolecular reactions of nitrilimines as a fruitful source of heterocycles. ... The multiform intramolecular reactivity of nitrilimines is presented in a systematic way, giving emphasis to its versatile potential in heterocyclic synthesis. ... Asymmetric synthesis of (R)(-)-dimethyl citramalate. ...
