Preparation of optically active (R)- and (S)-allene-1,3-dicarboxylates and their asymmetric cycloaddition reactions with cyclopentadiene

Optically active (R)- and (S)-allene-1,3-dicarboxylates were prepared, and their asymmetric Diels-Alder reactions with cyclopentadiene in the presence of Lewis acid proceeded to afford the endo-adducts in high yields. The absolute configuration of the add
