Manganic acetate and potassium methyl malonate with a 2-substituted dihydropyran provide the corresponding fused gamma-lactone in good yield. Carboxylic acids with less acidic methylene protons fail in this reaction.
The present invention relates to quinazolinones and related compounds which are inhibitors of PARP14 and are useful, for example, in the treatment of cancer and inflammatory diseases.
