Description

Application

1,3-Cyclohexanedione can be used as a building block in the synthesis of:

• 9-substituted 1,8-dioxo-xanthenes by reacting with unactivated aldehydes via aldol condensation/ Michael addition reaction.
• [(1,2,3-triazol-4-yl)methoxy-phenyl]-2H-indazolo[2,1-b]phthalazine-trione derivatives by treating with phthalhydrazide, aromatic propargyloxy aldehydes, and azides via a four-component condensation reaction.

It can be also used to prepare 2-substituted adducts, which are important intermediates for the synthesis of ß-enaminones , polyhydroquinoline derivatives , 1,8-dioxo-dodecahydroxanthenes , spirocyclopentanols , oxathioles , and triquinanes.
