Dieter, R. Karl published the artcileAsymmetric Synthesis of Enantioenriched (+)-Elaeokanine A, Application In Synthesis of 69361-41-7, the publication is Journal of Organic Chemistry (2006), 71(15), 5674-5678, database is CAplus and MEDLINE.
The key transformation in the total synthesis of (+)-elaeokanine A (I, R = COCH2Et) was accomplished by asym. deprotonation of N-Boc pyrrolidine, followed by the reaction of the in situ generated enantioenriched stereogenic cuprate reagent with (E)-4-bromo-1-iodo-1-trimethylsilyl-1-butene with retention of configuration. N-Boc deprotection, followed by a one-pot olefin isomerization and intramol. amine alkylation afforded bicyclic vinyl bromide I (R = Br) that was converted into (+)-elaeokanine A by sequential halogen metal exchange and reaction of the organolithium reagent with N-butanoylmorpholine.
