Tropolone is an organic compound with the chemical formula C 7 H 5 (OH)O. It is a pale yellow solid that is soluble in organic solvents. It is a pale yellow solid that is soluble in organic solvents. The compound has been of interest to research chemists because of its unusual electronic structure and its role as a ligand precursor.
Tropone or 2,4,6-cycloheptatrien-1-one is an organic compound with some importance in organic chemistry as a non-benzenoid aromatic. [2] The compound consists of a ring of seven carbon atoms with three conjugated alkene groups and a ketone group.
Tropolone is a grape polyphenol oxidase inhibitor. [20] Another inhibitor of this enzyme is potassium metabisulfite . [ 21 ] Banana root PPO activity is strongly inhibited by dithiothreitol and sodium metabisulfite , [ 22 ] as is banana fruit PPO by similar sulfur-containing compounds including sodium dithionite and cysteine , in addition to ...
Aromaticity is found in ions as well: the cyclopropenyl cation (2e system), the cyclopentadienyl anion (6e system), the tropylium ion (6e), and the cyclooctatetraene dianion (10e). Aromatic properties have been attributed to non-benzenoid compounds such as tropone. Aromatic properties are tested to the limit in a class of compounds called ...
Thujaplicin (isopropyl cycloheptatrienolone) is any of three isomeric tropolone-related natural products that have been isolated from the softwoods of the trees of Cupressaceae family. [1] These compounds are known for their antibacterial, antifungal, and antioxidant properties. [2] [3] They were the first natural tropolones to be made ...
Thujaplicinol is either of two isomeric tropolone-related natural products. They are found in tree species primarily in bark, needles, xylem, of the family of Cupressaceae like the Cupressus, Thuja, Juniperus and Thujopsis. [1] [2] The thujaplicinols are structurally equivalent to the thujaplicins with an additional hydroxyl group.
Stipitatic acid is a tropolone derivative isolated from Talaromyces stipitatus (Penicillium stipitatum). [1] References
Homoaromaticity, in organic chemistry, refers to a special case of aromaticity in which conjugation is interrupted by a single sp 3 hybridized carbon atom. Although this sp 3 center disrupts the continuous overlap of p-orbitals, traditionally thought to be a requirement for aromaticity, considerable thermodynamic stability and many of the spectroscopic, magnetic, and chemical properties ...
