trifluoromethylated DHP compounds. The reaction proceeded smoothly under mild electrolysis conditions. The broad substrate scope (>50 examples) and scalablesynthesis demonstrated the complexity-building potential of the strategy. Initial mechanistic studies reveal that cyclization may involve a radical process. This protocol may promote the further development of diversified synthesis of multi-substituted dihydropyran
