Meldrum's acid (2) is acylated by diketen affording the acyl Meldrum's acid 3.In aqueous bicarbonate its 3-oxogroup is selectively reduced by sodium tetrahydroborate giving the alcohol 4, which readily undergoes cyclization in refluxing dioxane leading to the title pyrone 7.Under identical conditions 3 produces the pyrone 6 with the pyrone carboxylic acid 5 as intermediate. - Keywords: Acyl Meldrum's acid; Ring closure; Selective reduction
