Carboxylic acid serving as both directing and leaving group was discovered in Ru-catalyzed decarboxylative annulations of α-keto acids with alkynes. The wellestablished protocol showed high functional group tolerance, which provided an efficient and alter

The direct oxidative coupling of 2-amino- and 2-hydroxybenzoic acids with internal alkynes proceeds efficiently in the presence of a rhodium/copper catalyst system under air to afford the corresponding 8-substituted isocoumarin derivatives, some of which
