Copper(І) hexafluorophosphate: a dual functional catalyst for three-component reactions of methyl phenyldiazoacetate with alcohols and aldehydes or α-ketoesters
摘要:
Oxonium ylides in situ generated from methyl phenyldiazoacetate and alcohols in the presence of CuPF6(CH3CN)(4) underwent an aldol-type reaction with aldehydes or alpha-ketoesters in a convergent, three-component fashion to give alpha-alkoxyl-beta-hydroxyl acid derivatives in good yields.
