摘要：
Lithim dihydropyranyl or dihydrofuranyl triorganoaluminates react with cyclohexene oxide or benzaldehyde in the presence of BF3. OEt2, not by nucleophilic attack product 1, but by 1,2 migration of α substituent from Al to the {plus sign in right half circle}-carbon, with concomitant reaction with the electrophile on the β-carbon, giving rise to product 2. © 1990.
