Abstract
trans-β-substituted γ-ferrocenyl-γ-butyrolactones were prepared via the reaction of quaternary ammonium salts with electron-deficient trisubstituted alkene 1 under the optimum conditions. Moderate to good yields and excellent trans stereoselectivity were achieved for the new compounds 2-10. The X-ray crystal structure of 2a was determined and all the products were characterized by 1H NMR, 13C NMR, FAB-MS, IR and HRMS spectra.
