Methylenedioxyphenyl unit displays a significant stereoelectronic effect in some key transformations in the total synthesis of cephalotaxine. The ring-strain of methylenedioxy ring may account for some important facile ring-skeleton rearrangements.
- Stereoelectronic effect,
- reductive rearrangement,
- cephalotaxine,
- total synthesis.
