We report the preparation of enantiomerically pure constrained geometry complexes (cgc) of the rare-earth metals bearing a pentadienyl moiety (pdl) derived from the natural product (1R)-(-)-myrtenal. The potassium salt 1, [Kpdl*], was treated with ClSiMe<sub>2</sub> NHtBu, and the resulting pentadiene 2 was deprotonated with the Schlosser-type base KOtPen/nBuLi (tPen=CMe<sub>2</sub> (CH<sub>2</sub> Me)) to yield the dipotassium salt [K<sub>2</sub> (pdl*SiMe<sub>2</sub> NtBu)] (3). However, 3 rea ...[more]
