Chemoselective Synthesis of β-Ketophosphonates Using Lithiated α-(Trimethylsilyl)methylphosphonate
摘要:
A highly chemoselective synthesis of beta-ketophosphonates from pentafluorophenyl esters and lithiated methyl alpha-(trimethylsilyl)methylphosphonate has been developed. This mild lithiated phosphonate reagent allows the synthesis of functionalized beta-ketophosphonates in the presence of unactivated esters with high yields. This method has been compared with the standard lithiated methylphosphonate reagent.
