  Multifunctional Cyclopentadienes as a Scaffold for Combinatorial Bioorganometallics in [(η ⁵ ‐C ₅ H ₂ R ₁ R ₂ R ₃ )M(CO) ₃ ] (M=Re, ^99m Tc) Piano‐Stool Complexes

  摘要：

  AbstractMultifunctional cyclopentadiene (Cp) ligands and their rhenium and 99mTc complexes were prepared by a versatile synthetic route. The properties of these Cp ligands can be tuned on demand, either during their synthesis (variation of R1) or through post‐synthetic functionalization with two equal or different vectors (V1 and V2). Variation of these groups enables a combinatorial approach in the synthesis of bioorganometallic complexes. This is demonstrated by the preparation of Cp ligands containing both electron‐donating and electron‐withdrawing groups at the R1 position and their subsequent homo‐ or heterofunctionalization with biovector models (benzylamine and phenylalanine) under standard amide bond‐formation conditions. All ligands can be coordinated to the fac‐[Re(CO)3]+ and fac‐[99mTc(CO)3]+ cores to give tetrafunctional complexes in straightforward and functional‐group‐tolerant procedures. The 99mTc complexes were prepared in one step, in 30 min, and under aqueous conditions from generator‐eluted [99mTcO4]−.
