acetates with aldehydes, was presented. Simple bench-top aldehydes were used as the non-toxic acylating agents. This protocol comprises direct coupling with aldehydes without activating the carbonyl group and without the directing group assistance. The strategy was applied to a domino one-pot synthesis of 2-quinolinones via acylation and intramolecular aldol condensation. Significantly, the strategy was extended
