Tropolon je hidroksiderivat tropona. Obstajajo trije tropoloni, odvisno od mesta vezave hidroksilne skupine.
Sinteza tropolona poteka na dva načina: 1. z bromiranjem 1,2-cikloheptandiona (uporabimo N-Bromosukcinimid in kasnejšo dehidrohalogenacijo pri zvišani temperaturi; 2. z akiloinsko kondenzacijo etilestra pimelične kisline in akiloina ter kasnejšo oksidacijo z bromom.
Sinteza tropolona
α-tropolon je inhibitor grozdne polifenol oksidaze.[2][3]
