Thermal transformation of cyclopropylazoarenes into the five-membered nitrogen-containing heterocycles

Cyclopropylazoarenes containing methoxy groups in the aromatic ring give the corresponding N-arylpyrazolines on the reflux in o-dichlorobenzene or on SnCl2 catalysis at 80 °C in good yields. The products can be smoothly oxidized into the corresponding pyrazoles. Thermolysis of cyclopropylazoarenes containing hydroxy groups in the aromatic ring proceeds more complicated. Thus in the case of resorcin azo derivative, strong resinification of the reaction mixture is observed and the corresponding N-arylpyrazoline is isolated only in -40% yield. Under similar conditions, thermolysis of 1-cyclopropyl- and 1-(1-methylcyclopropyl)azo-2-naphthol proceeds otherwise and unexpectedly leads to naphtho[1,2-d]oxazole derivatives with degradation of the cyclopropane ring.

Cyclization of α-Oxo-oximes to 2-Substituted Benzoxazoles

Reactions of oximes 9, 17, and 19 with electrophiles 15a-f and 24 in the presence of anhydrous potassium carbonate or triethylamine give 2-substituted condensed ring oxazoles 10, 16a-c, 18a-d, 20a-c, and 25 in a new general route to these compounds.

Reaction of silyl enol ethers with xenon difluoride in MeCN: Evidence for a nonclassical radical cation intermediate

(matrix presented). The reactions of xenon difluoride in MeCN solution in Pyrex flasks with a series of TMS enol ethers have been investigated. The types of products formed are dependent on the structures of individual enol ethers, but under these conditions all products are consistent with a mechanism involving single electron transfer to un-ionized XeF2 giving a radical cation and subsequent formation of an α-fluoroketone, together with some ketone formation. The results suggest that if the radical cation is particularly stable, fluorodesilylation leads to radical formation, and solvent-derived products are then observed. Using other solvents, such as CFCl3 and C6F6, much more complex mixtures of products are obtained, and this is attributed to a different mode of reaction of xenon difluoride involving ionization to FXe+.

Method for preparing 2-lower alkyl-substituted naphthoxazoles by way of non-toxic intermediates

The invention relates to a method for preparing 2-lower alkyl-substituted naphthoxazoles by way of non-toxic intermediates, and in particular relates to the preparation of a 2-lower alkyl-naphtho-[2,1-d]-oxazole or a 2-lower alkyl-naphtho-[1,2-d]-oxazole, which are of industrial interest in the field of cyanine dyes for use in photography, and in the field of optical brighteners for use in plastic materials. According to the invention, an aldehyde of a lower alkyl is reacted with 2-nitroso-1-naphthol or with 1-nitroso-2-naphthol, in the presence of a strong acid and a non-aqueous organic solvent, and the condensation product is then reduced.
