  • Title: Phosphine-catalyzed domino reaction: an efficient method for the synthesis of highly functionalized spirooxazolines.
    Author: Yang L, Xie P, Li E, Li X, Huang Y, Chen R.
    Journal: Org Biomol Chem; 2012 Oct 07; 10(37):7628-34. PubMed ID: 22903685.
    Abstract:
    A novel phosphine-catalyzed intermolecular [3 + 2] cycloaddition of ynones and N-substituted isatins was developed. In this reaction, substituted ynones, serving as a C(3) synthon, were successfully applied in intermolecular annulation reactions. A number of functionalized spirooxazolines were obtained in high yields and stereoselectivity.
