Synthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone
An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...

wide interest because the 1H-pyridin-2-ones obtained in this process are versatile synthetic building blocks in the synthesis of alkaloids.1–5 The title compound, (–)-(1′R)-1-(2′-hydroxy-1′-phenyl-ethyl)1H-pyridin-2-one II, was prepared by stirring a solution of pyridinium salt, I (4.0 mmol), in water (25 ml) and cooled to 5 ̊C (Scheme 1). A solution of K3Fe(CN)6 (11 eq.) in water (30 ml) was ad...
متن کاملBis{2-[1-(8-hydroxy-2-quinolylmethyl)-1H-benzimidazol-2-yl]quinolin-8-ol} toluene solvate
Crystals of the title compound, 2C(26)H(18)N(4)O(2)·C(7)H(8), were obtained from the reaction of 8-hydroxy-quinoline with 1,2-phenyl-enediamine in methanol and recrystallized from toluene. The compound contains three essentially planar ring systems: the benzimidazole ring (r.m.s. deviation = 0.039 Å) and two 8-hydroxy-quinoline rings (r.m.s. deviations of 0.0056 Å in both rings). The benzimidaz...
متن کاملEfficient Synthesis of a Range of 1-Hydroxy-2-(1-Alkyloxymethyl)-9,10-Anthraquinone Derivatives
Five new 1-hydroxy-2-(1-alkyloxymethyl)-9,10-Anthraquinones (9a-e) have been prepared. Selective nitration of 2-methyl-9,10-anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-2-methyl-9,10-anthraquinone in good yield as the key intermediate. Reaction with dimethylsulphate/K2CO3 and subsequen...
متن کامل(E)-3-(2,3-Dimethoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one
The mol-ecular conformation of the title compound, C(18)H(18)O(5), is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The C=C double bond displays an E configuration while the carbonyl group shows an S-cis configuration relative to the double bond. The dihedral angle between the two rings is 15.0 (1)°.
