title: Total syntheses of (±)-α-lycorane and (±)-1-deoxylycorine.
abstract: New synthetic routes to (±)-α-lycorane and (±)-1-deoxylycorine were exploited. The endo-cycloadduct of 3,5-dibromo-2-pyrone with styrene-type dienophile provided the pivotal intermediate for the syntheses of the titled natural products.
