Abstract :
One-pot efficient synthesis of functionalized 5,6-dihydropyran-2-ones has been delineated by reacting 2H-pyran-2-ones and acetol in the presence of a base at room temperature. The formation of 5,6-dihydropyran-2-ones revealed that the reaction proceeded in a unique ‘ring transformation-rearrangement’ sequence.
