The conversion of car☐ylic acids to keto phosphorane precursors of 1,2,3-vicinal tricarbonyl compounds
摘要:
Acyl phosphoranylidines react with acid chlorides or anhydrides in the presence of bis(trimethylsilyl)acetamide (BSA), or couple directly with carboxylic acids activated by EDCI to give keto phosphoranes 1.
