摘要：

Diels-Alder reactions of silyloxydiene 1 derived from 1-acetylcyclohexene with imines 2b and 2c occur with high exo selectivity depending upon experimental conditions: exo cycloadducts 3b-c are exclusively formed under kinetic control using tert-butyldimethylsilyltriflate as catalyst. In the presence of AlCl3, under thermodynamic control, high endo selectivity is only observed with 2b.
