Towards a total synthesis of (-)-cephalotaxine: Construction of the BCDE-tetracyclic core

The synthesis of the BCDE-tetracyclic core of (-)-cephalotaxine has been achieved in eight steps starting from N-Boc-L-proline methyl ester. An alkylidene carbene 1,5-CH insertion reaction was used as a key step in the stereocontrolled synthesis of the DE
