Diastereoselective oxidative cyclization of 1,4-dienes for the synthesis of oxetanes

Key Points

• The study aims to explore the diastereoselective oxidative cyclization of 1,4-dienes to produce oxetanes.
• Utilized osmium as a catalyst for the oxidative cyclization process.
• Focused on exo,exo-type cyclization of 1,4-dienes.
• Explored the formation of oxetanes as products.
• Oxetanes were obtained as oxidative cyclization products for the first time.
• The reaction demonstrates diastereoselectivity in product formation.
