Benzoylierung an 3-8ubstituierten 4-Hydroxy-2-chinolonen und 4-Hydroxycumarinen Benzoylation of 3-Substituted 4-Hydroxy-2-quinolones and 4-Hydroxycoumarines
Die Acetylierung von 4-Hydroxycumarinen und verwandten Verbindungen, die schon mehrmals Gegenstand eingehender Untersuchungen war, zeigt, daß bei kinetisch kontrollierten Bedingungen das 4-Acetoxyderivat entsteht, während als thermodynamisch stabileres Produkt die 3-Acetylverbindung gebildet wird [1, 2], Analoge Ergebnisse werden auch bei der Acylierung mit anderen aliphatischen Carbonsäuren ge...

A novel compound involved in the aroma of the fruit Campomanesia lineatifolia was isolated; the structure was determined by spectroscopic methods, mainly 1D and 2D NMR.
متن کاملSYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID
Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
متن کامل1-Methyl-4-(4-methylstyryl)pyridinium 4-methylbenzenesulfonate
In the title salt, C15H16N(+)·C7H7O3S(-), the dihedral angle between the pyridine and benzene rings of the cation is 5.98 (18)°. In the crystal, adjacent anions and cations are linked by weak non-classical C-H⋯O hydrogen bonds and π-π inter-actions, with a centroid-centroid distance of 3.749 (2) Å.
متن کاملN-(4-Fluorobenzoyl)-2-hydroxy-4-methylbenzohydrazide
In the title compound, C(15)H(13)FN(2)O(3), the aromatic rings are aligned at an angle of 10.15 (3)°. The mol-ecules are packed with π-π stacking inter-actions [mean inter-planar distances of 3.339 (2) and 3.357 (3) Å] and the crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. An intramolecular N-H⋯O interaction also occurs.
