Abstract

The reductive cyclization of epoxygeranyl acetate (1) was investigated using a catalytic amount of Cp₂TiCl with various additives. The newly developed Cp₂TiCl-Mn-lutidine·HCl-BEt₃ system was found to be as effective as the reported stoichiometric system to afford the cyclized dehydro products 4 and 5 with 72% selectivity.
