Regiochemical control in the homo-Diels-Alder reaction: substituent effects
摘要:
The regio- and stereoselectivity of the cyclo-addition between substituted norbornadienes and electron-deficient olefins catalyzed by nickel complexes has been studied. The diene and dienophile substituents as well as the ligand were found to exert a dramatic effect on the selectivity.
