The first asymmetric total syntheses of (+)-lycorine and (+)-1-deoxylycorine

The first asymmetric total syntheses of (+)-1-deoxylycorine (2a) and (+)-lycorine (2b), the unnatural enantiomer of lycorine (1), are described. Construction of lactam 12, a key intermediate in the synthesis of both 2a and 2b, began by Birch reduction-alk
