Quinoline N-oxides (1) react with 2-thiobarbituric acid (2) in Ac2O-DMF or in Ac2O alone to afford regioselectively 2-substituted quinolines (3) or quinolinium ylides (4) depending on the nature of 1 and the reaction conditions.The reaction of quinoline, lepidine, 4-chloroquinoline and 4-methoxyquinoline N-oxide with 2 in Ac2O-DMF at room temperature or at 90 deg C gives the corresponding N-ylides (4).The directive influence of the reaction medium becomes reverse when Ac2O is used alone at room temperature or at 90 deg C.While 3-cyanoquinoline N-oxide (1g) gives only 2-substituted quinoline (3g), 4-morpholino- and 3-bromo-quinoline N-oxides (1e,f) afford N-ylides (4e,f) independently of the reaction conditions.Furthermore, isoquinoline 2-oxide (7) readily reacts with 2 under different conditions to give invariably the 1-substituted isoquinoline (8).Pyridine N-oxide gives only 5-dimethylaminomethylene-2-thiobarbituric acid (9) on reaction with 2 in Ac2O-DMF at room temperature.

Isoquinoline 2-oxide (1) reacts with cyanoacetic acid in the presence of Ac2O to afford various types of 1-substituted isoquinolines (2, 4, 6, and 7) and N-ylides (3 and 5a) depending upon the reaction conditions and processing procedures (Table I).The reaction in Ac2O gives initially alpha-acetoxycarbonyl-1-isoquinolineacetonitrile (2) and 2-isoquinolinio-acetoxycarbonylcyanomethylide (3), and that in Ac2O-dimethylformamide yields only 3.Products 2 and 3 are readily convertible into alpha-acetyl-1-isoquinolineacetonitrile (4) and 2-isoquinolinio-acetylcyanomethylide (5a), respectively, by processing involving heating.The reaction in ethanol gives ethyl alpha-cyano-1-isoquinolineacetate (6) and di(1-isoquinolyl)acetonitrile (7).The reaction of 1 with benzoylacetonitrile affords both the corresponding 1-substituted isoquinoline (10) and N-ylide (11).Reactions with ethyl benzoylacetate and, methyl and ethyl acetoacetates produce 1-substituted isoquinolines (12 and 14a, b) and 4-acetoxyisoquinoline (13), no ylide being formed.Keywords – isoquinoline 2-oxide; nucleophilic reaction; decarboxylative acyl migration; alpha-acetoxycarbonyl-1-isoquinolineacetonitrile; alpha-acetyl-1-isoquinolineacetonitrile; ethyl alpha-cyano-1-isoquinolineacetate; alpha-benzoyl-1-isoquinolineacetonitrile; 2-isoquinolinio-acetoxycarbonylcyanomethylide; 2-isoquinolinio-acetylcyanomethylide; 2-isoquinolinio-benzoylcyanomethylide.

The review (Part 1) deals with the synthesis of 2-pyridone methides and benzo-fused analogs. Methides that are unsubstituted at the nitrogen atom are mainly synthesized from the corresponding pyridine bases by reactions at o- or alpha-positions, from N-oxides or by ring formation or transformation. N-Substituted so-called anhydrobases mostly originate from quaternary salts either by deprotonation or by reactions at o- or alpha-positions.

A novel approach was developed for the dehydrogenative etherification homocoupling of heterocyclic N-oxides in the presence of silver oxide and PyBroP. Various substrates were well tolerated and the desired products were obtained in moderate to good yields. Generally, this reaction features excellent functional group compatibility, broad substrate scope and good regioselectivity.

N-Oxides are a class of highly important compounds that are used widely as synthetic intermediates. In this paper, we demonstrate for the first time the use of a polyoxometalate-based composite material as a highly efficient heterogeneous catalyst for the N-oxidation of pyridines and its derivatives in the presence of H2O2 at room temperature. The composite was prepared by the intercalation of the [La(PW11O39)2]11- anion into a layered double hydroxide (LDH) modified with tris(hydroxymethyl)aminomethane (Tris). Additionally, the Tris-LDH-La(PW11)2-based catalyst has been employed for the denitrogenation of a model oil mixture in the presence of 1-butyl-3-methylimidazolium tetrafluoroborate and H2O2. Denitrogenation can be achieved in 40 min at 75 C. Finally, the heterogeneous catalyst can be recovered easily and reused at least 10 times without a measurable decrease of the catalytic activity and disintegration of the Tris-LDH-La(PW11)2 structure.

alpha-Benzotriazolyl-substituted pyridines, -quinolines and -isoquinolines have been prepared by reactions of pyridine, quinoline and isoquinoline N-oxides with 1-tosylbenzotriazole in the presence of triethylamine. Treatment of alpha-benzotriazolylpyridines, -quinolines and -isoquinolines with hydrogen peroxide in glacial acetic acid afforded N-oxides, the structures of which were determined by X-Ray crystallography. Reactions of 1-(2-pyridinyl)-benzotriazole with alkyl halides or tosylates led to the corresponding N-alkylpyridinium salts.

Twenty one ternary complexes of lanthanide with 3,5-di-tert-butyl-gamma-resorcylic acid (L) and seven different substituted pyridine-N-oxides (L1-7), with compositions of REL3L1-72·nH2O (RE=Nd, Gd, Er; L1=4-picoline-N-oxide; L2=4-phenyl-pyridine-N-oxide; L3=pyridine-N-oxide; L4=3-picoline-N-oxide; L5=quinoline-N-oxide; L6=iso-quinoline-N-oxide; L7=4-methoxyl-pyridine-N-oxide; n=0, 1, 2, 5), were synthesized and characterized by means of elemental analysis, electrical conductivity, thermal analysis and IR spectra. The novel crystal structure of ErL3L32·(EtOH) has been determined by a single-crystal X-ray diffraction method. It shows that each erbium ion is linked to three 3,5-di-tert-butyl-gamma-resorcylic acid ions through two different types of dentation modes in which only the carboxylate oxygen atoms participate. The coordination geometries of erbium ion can be described as a distorted octa-coordinated bicapped trigonal prism. Elsevier Science Ltd.
