Gold(I)‐Catalyzed Regio‐ and Stereoselective 1,3‐Dipolar Cycloaddition Reactions of 1‐(1‐Alkynyl)cyclopropyl Oximes with Nitrones: A Modular Entry to Highly Substituted Pyrrolo[3,4‐
An efficient approach for the synthesis of highly substituted pyrrolo[3,4‐d][1,2]oxazepines has been achieved by gold(I)‐catalyzed 1,3‐dipolar cycloaddition reactions of 1‐(1‐alkynyl)cyclopropyl oximes with nitrones in good to excellent yields as a single diastereomer. A complete chirality transfer was observed in this transformation.
