Resumo

A facile and convenient synthesis of dihydropyranones has been developed by a formal [4+2] annulation of readily available alpha-acetyl ketene S,S-acetals with various aldehydes, involving a tandem aldol reaction and conjugate addition-elimination reaction, in the presence of NaOH in water.
