Three-component coupling sequence for the regiospecific synthesis of substituted pyridines

A de novo synthesis of substituted pyridines is described that proceeds through nucleophilic addition of a dithiane anion to an α,β- unsaturated carbonyl followed by metallacycle-mediated union of the resulting allylic alcohol with preformed trimethylsilane-imines (generated in situ by the low-temperature reaction of lithium hexamethyldisilazide with an aldehyde) and Ag(I)- or Hg(II)-mediated ring closure. The process is useful for the convergent assembly of di- through penta-substituted pyridines with complete regiochemical control.

(η3-Allyl)(η5-pentamethylcyclopentadienyl)cobalt - a Selective Catalyst for the Pyridine Synthesis

(η3-Allyl)(η5-pentamethylcyclopentadienyl)cobalt (1) cactalyses the synthesis of various pyridines from alkynes and nitriles under mild conditions.Only small amounts of benzenes are formed in this selective reaction. - Key Words: Cobalt complexes, (η3-allyl)(η5-pentamethylcyclopentadienyl)- / Pyridine synthesis / Catalytic activity / Chemoselectivity
