| Abstract
| - Allylation reaction of electron-deficient imines with allylic alcohol derivatives in the presence of acatalytic amount of palladium(0) complex and indium(I) iodide was studied. The reversibility ofallylation was observed in the reaction of glyoxylic oxime ether having camphorsultam. As theimportant effect of water on regioselectivity, the γ-adducts were kinetically formed from monosubstituted allylic reagents in the presence of water. The selective formation of thermodynamicallystable α-adducts was observed in anhydrous THF. In contrast, the allylation of N-sulfonyliminegave the γ-adducts with high regioselectivities even under anhydrous reaction conditions.
