SYNTHESIS 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 کاملCrystal structures of 4-methoxy-6-methyl- and 4-hydroxy-6-methyl-2-pyrones.
interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
متن کاملSynthesis of gefitinib from methyl 3-hydroxy-4-methoxy-benzoate.
This paper reports a novel synthesis of gefitinib starting from methyl 3-hydroxy-4-methoxybenzoate. The process starts with alkylation of the starting material, followed by nitration, reduction, cyclization, chlorination and two successive amination reactions. The intermediates and target molecule were characterized by 1H-NMR, 13C-NMR, MS and the purities of all these compounds were determined ...
متن کاملSynthesis and evaluation of 6-hydroxy-7-methoxy-4-chromanone- and chroman-2-carboxamides as antioxidants.
A series of 6-hydroxy-7-methoxy-4-chromanone- (2a-e) and chroman-2-carboxamides (3a-e) were synthesized and their antioxidant activities were evaluated. While compounds 2a-e were less active, compounds 3a-e exhibited more potent inhibition of lipid peroxidation initiated by Fe(2+) and ascorbic acid in rat brain homogenates. Among them, N-arylsubstituted-chroman-2-carboxamides (3d and 3e) exhibi...
