Gewald, K.,Rehwald, M.,Mueller, H.,Bellmann, P.,Schaefer, H.
, p. 341 - 348 (1995)
Arylhydrazono acetamides 1 react with chloroacetic acid chloride to give N-chloroacetyl derivatives 2.Subsequent reaction with pyridines followed by ring closure yield 1-(4-amino-6-oxo-pyridazin-5-yl)-pyridinium chlorides 3.Analogously, 1-(6-oxo-pyridazin

Gewald, Karl,Rehwald, Matthias,Gruner, Margit
, p. 457 - 464 (2007/10/02)
Reaction of tetrahydrothiophene with the N-(iodoacetyl)anthranilic acid derivatives 1a, b and 2-(iodoacetylamino)acetophenone (1c) yields the 1-(2-oxoquinolin-3-yl)tetrahydrothiophenium salts 3a-c in two steps.Analogously the heterocondensed 1-(2-oxopyrid
Novel synthesis of substituted chloro-3-(2H)-pyridazinones from pentane-2,3,4-trione 3-arylhydrazones
