Dioxindole in asymmetric catalytic synthesis: routes to enantioenriched 3-substituted 3-hydroxyoxindoles and the preparation of maremycin A.
摘要：
Taming the reactivity: Understanding the nucleophilicity of dioxindole under different reaction conditions is key to a direct and easy access to valuable spiro oxindole butyrolactones and 3-substituted 3-hydroxyoxindole derivatives in excellent yields and enantioselectivities (see scheme). The preparation of maremycinA serves as an example for the potential usefulness of this previously unexplored reactivity in natural product synthesis.
