Aj. Pearson et al., STEREOCONTROLLED CYCLIZATION OF UNACTIVATED ALKENE ONTO CATIONIC DIENYL IRON TRICARBONYL SYSTEMS, Tetrahedron letters, 39(33), 1998, pp. 5919-5922
Treatment of pentadienol-Fe(CO)(3) complexes, having alkene functional
ity in the side chain, with boron trifluoride, results in a stereospec
ific cyclization by reaction of the alkene with a stabilized carbocati
on intermediate; the stereochemical outcome was confirmed by X-ray str
ucture determination of one of the products. (C) 1998 Elsevier Science
