Malonic acid derivatives undergo unusually mild decarboxylation when treated with N,N′-carbonyldiimidazole (CDI) at room temperature to generate the carbonyl imidazole moiety in high yield, which can be reacted further with a variety of nucleophiles in an efficient one-pot process.

Review

Wide versatility and good reproducibility

This work by Lafrance and co-work represents a very mild means to induce the decarboxylation of malonic acid derivatives with 1,1-carbonyldiimidazole (CDI). The reactive intermediate carbonyl imidazole moiety can be trapped with various nucleophiles in an effcient one-pot...
