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.
