A piperidinium acetate-catalyzed method was developed for the Knoevenagel and O-Micheal cascade reaction of o-hydroxyphenyl-β-diketoes with different series of aldehydes. In the presence of piperidinium acetate, sixteen 2,3-disub-stituted chroman-4-ones and nine 2,2-disubstituted benzofuran-3-ones were obtained in moderate to good yields, and the cascade reaction displayed better substrate adaptability. Moreover, the reaction has the following features: a convenient and simple path, mild reaction conditions and a cheap catalyst.

Key words: piperidinium acetate, cascade reaction, chroman-4-one, benzofuran-3-one
