Allylation and benzylation of enolates derived from β-phenylselanyl silyl enol ethers
摘要:
alpha-Phenylselanyl gamma-unsaturated ketones were obtained through allylation of enolates generated by potassium t-butoxide cleavage of beta-phenylselanyl silyl enol ethers derived from alpha-phenylselanyl ketones. With enoxysilanes prepared from alpha-phenylselanyl aldehydes, O-allylation and O-benzylation of the corresponding enolates were also observed. (C) 1997 Elsevier Science Ltd.
