Bistrifluoromethanesulfonimide in the catalytic conjugate allylation of α,β-unsaturated carbonyl compounds
摘要:
Bistrifluoromethanesulfonimide may be used directly to initiate the catalytic conjugate allylation of alpha,beta-unsaturated carbonyl compounds with allyltrimethylsilane; high yields of either silyl enol ethers or delta,epsilon-unsaturated ketones and esters may be obtained under mild conditions.

Samarium(II) iodide (SmI2)-promoted ketyl cyclizations of several substituted, unsaturated ketones, providing various cyclopentyl and cyclohexyl systems, have been investigated. The resulting experiments provide stereochemical insight into these reactions and in addition outline the synthetic potential of these 5-exe and 6-exo radical cyclization processes.
