3-acetyl-7-dimethylaminocoumarin

Description

3-acetyl-7-dimethylaminocoumarin is a coumarin-based building block. Ring heteroatoms redistribute electron density, dipole and hydrogen-bonding capacity relative to an all-carbon analogue – which is the reason a heterocyclic core gets chosen where a carbocycle would be geometrically equivalent but electronically wrong.

Key data

• Catalogue code: KC1038
• Molecular formula: C13H13NO3
• Molecular weight: 231.25 g/mol
• Category: Heterocycles

What the substitution pattern does

The coumarin (2H-chromen-2-one) core is a fused benzopyranone with strong absorption in the near-UV and emission in the visible. Substitution at the 3- and 7-positions is the classical way to tune that emission, which is why this ring system recurs in laser dyes and fluorescent probes.

Typical applications

• fluorescent probes and laser dyes where the coumarin motif applies
• cross-coupling substrates carrying a pre-installed heteroatom
• materials chemistry requiring a polar, planar ring system
• heterocyclic cores for mesogens with tailored dipole and polarisability
• ligand and pharmacophore construction in discovery chemistry
