Application
Samarium(II) iodide solution (SmI2) can be used as a reagent in the synthesis of:
- Benzannulated pyrrolizidines and indolizidines by SmI2-induced cyclizations of indole derivatives.
- Chiral 4-substituted 2-oxazolidinones and 5,5-disubstituted oxazolidinones through asymmetric Reformatsky type reaction.
- γ-Aminoalkyl substituted γ-butyrolactones via ketyl-alkene coupling reaction.
It can also be used in:
- Reduction of conjugated double and triple bonds into alkenes using SmI2/H2O/amine mixtures.
- Conversion of β-hydroxyketones into 1,3-diols by SmI2/H2O/Et3N.
- Selective reduction of 6-membered lactones to the corresponding diols/triols using SmI2-H2O reagent system.
SmI2 is an effective single-electron reducing agent for the promotion of ketone-olefin, ketyl aryl cyclizations, and pinacol coupling reactions under mild conditions. Often both intramolecular and intermolecular couplings proceed in a highly stereoselective fashion. It is also used in the synthesis of new heteroleptic samarium aryloxide/cyclopentadienide complexes.
