Convergency and divergency as strategic elements in total synthesis: the total synthesis of (-)-drupacine and the formal total synthesis of (+/-)-cephalotaxine, (-)-cephalotaxine, and (+)-cephalotaxine.
A concise route toward the syntheses of (-)-drupacine and (+)- and (-)-cephalotaxine has been developed. The syntheses rely on Pd(II)-catalyzed aerobic oxidative heterocyclization chemistry, which was employed to rapidly construct an important spirocyclic amine intermediate. A dynamic beta-elimination/conjugate addition process was strategically applied to complete the first asymmetric total synthesis of (-)-drupacine.

[Synthesis and antitumor activity of the derivatives of cephalotaxine and drupacine].
To make full use of cephalotaxus plant resources and search for antitumor agents with higher activities and lower side effects.. The C3 hydroxy groups of the cephlotaxine and drupacine were acylated by taxol side chain and its isomers to give a series of derivatives of cephlotaxine and drupacine.. Six novel alkaloid esters were designed and synthesized. The pharmacological screening results showed that VIIIa, VIIIb, IXa and IXc exhibited significant activities on KB, HCT and Bel in vitro.. Novel alkaloid esters are worthy to be intensively studied.
