1. Remarkably complex and unpredictable cyclization and rearrangement reactions of cations derived from unsaturated oxiranes

Author

E. J. Corey and Bryan E. Roberts

Subjects
Computational chemistry, Chemistry, Organic Chemistry, Drug Discovery, Biochemistry, Catalysis
Abstract

Lewis-acid catalyzed reactions of unsaturated epoxides 1 and 2 afford the unprecedented products 3 and 5, respectively. Mechanistic pathways for these reactions are presented (Schemes 2 and 4) along with a more fundamental analysis.
