β‐Keto Acids in Organic Synthesis

Recent advances of β ‐keto acids were summarized as five categories according to their triggered mechanisms: (1) decarboxylative enolate nucleophiles; (2) addition without decarboxylation; (3) electrophilic acids; (4) nucleophilic acids; (5) electrophilic ketones. We hope this review will promote future research in this area.
