title: Highly diastereoselective and enantioselective formal [4 + 1] ylide annulation for the synthesis of optically active dihydrofurans.
abstract: On the basis of the reactions of camphor-derived sulfur ylide with alpha-ylidene-beta-diketones, highly efficient and selective synthesis of optically active dihydrofurans has been achieved.
