Interception of Photochemical Intermediates of Thiazole Derivatives. Formation and Isomerisation of Iminoazetine and Azetinone Intermediates

, p. 1558 - 1559 (1984)
Irradiation of 4-aminothiazolium salts (7) in the presence of tributylphosphine gave enaminonitriles (9) and benzoylacetonitrile (8) by isomerisation and hydration of the iminoazetine intermediates (11), while a similar irradiation of the mesoionic triphenylthiazolium-4-olate (1) gave the quinolinol (5) by isomerisation of the azetinone intermediate (3).

β-Enaminonitriles react with substituted benzenediazonium tetraphenylborates to form 1,2,4,3λ4-triazaborines or 1,3,2λ4-oxazaborines. The formation of either the first or the second product is affected by the reaction conditions, esp

Methylazide reacts with the title olefines and gives expected 1,2,3-triazolines in equilibrium with corresponding amino dizao compounds.Because this equilibrium, E and Z olefines gives the same result, and the addition do not seem stereospecific.Thermolys
PHOTOCHEMICAL AND THERMAL REACTIONS OF HETEROCYCLES. PART 5. PRODUCTS VIA TRANSIENT QUASIANTIAROMATIC AZETINE INTERMEDIATES GENERATED BY DESULPHURISATION OF PHOTOCHEMICAL INTERMEDIATES FROM A THIAZOLIUM-4-OLATE AND 4-AMINOTHIAZOLIUM SALTS

Irradiation of the mesoionic triphenylthiazolium-4-olate (3) in the presence of tributylphosphine gave the quinolinone (7).This result was interpreted as arising via desulphurisation of the bicyclic intermediate (4) to the azetone (5), followed by its isomerisation to the ketene (6) and internal trapping.Similar irradiation of the 4-aminothiazolium salts (15) gave enamino nitriles (17) and benzoylacetonitrile (16).They are probably formed by isomerisation and hydration of the hitherto unknown quasiantiaromatic 2-imino-1,2-dihydroazete intermediates (20), which in turn are generated by desulphurisation of the bicyclic photochemical intermediates (19).
