Abstract

Group 3 and lanthanide metallocenes have been extensively investigated as catalysts promoting highly stereoselective cyclization/silylation reactions of monosubstituted and 1,1-disubstituted 1,5- and 1,6-dienes to functionalized carbocycles. 1 However, the synthetic utility of the organolanthanide-promoted cyclization/silylation reaction suffers from the fact that in some cases conversion of the organosilanes to the corresponding alcohols proved to be difficult. 2 ...
