Synthesis and pharmacological activities of some condensed 4-chloro-2,2-dialkyl chromene-3-carbaldehyde derivatives

Novi hidrazono- 5a,b, tiosemikarbazono- 6a-c i oksimo kromeni 7a-c sintetizirani su iz odgovarajućeg β-klorkarbaldehida 3 i hidrazina, aromatskog hidrazina, tiosemikarbazida ili hidroksilamin hidroklorida, dok su eterski derivati 8a-h pripremljeni iz pripadajućih aldoksima 7a-c. Novi spojevi ispitani su na protuupalno i ulcerogeno djelovanje, a njihovo djelovanje uspoređeno je s djelovanjem indometacina.Some new hydrazono- 5a,b, thiosemicarbazono- 6a-c, and oximo chromenes 7a-c were prepared via the reaction of the corresponding β-chlorocarbaldehyde 3 with hydrazine, aromatic hydrazine, thiosemicarbazide and hydroxylamine hydrochloride, respectively. In addition, ether derivatives 8a-h were prepared from the corresponding aldoximes 7a-c. The new products were tested for anti-inflammatory and ulcerogenic score activities compared to indomethacin
