Über 2‐Aza‐chalkone

Abstract: Nr. 10/1953] K u h n , Hensel: Uber 2-Aza-chalkone 1333 wenig Ather vefiiihrt wurde. Das Rohprodukt (4.8 g) lieferte am vie1 kochendem Waseer 4.28 g feine farbloee Nadeln (39% d.Th.) vom Schmp. 166-167". Die Ammonolyse von 2.0 g der Tetraacetyl-Verbindung gab 1.46 g Ruckstand, aus dem durch Umkristallisieren aus & a n 0 1 0.93 g (65% d.Th.) farbloee Nadeln vom Schmp. 20&206O gewonnen wurden.Die iibrigen in den Tafeln veneichneten Glucoside sind in entsprechender Weiee dargestellt worden.

“…Chalcones are natural biocides (Geiger & Conn, 1945;Marian et al, 1947) and are well known intermediates in the synthesis of heterocyclic compounds exhibiting various biological activities (Srivastava et al, 1997;Kuhn & Hensel, 1953). Chalcones and their derivatives possess some interesting biological properties such as antibacterial (Ishida et al, 1960), antifungal (Mehata et al, 1978, insecticidal (Mudaliar & Joshi, 1995), anesthetic (Hosni & Saad, 1995), anti inflammatory, analgesic and ulcerogenic activities.…”

“…2-(5-Tetrazolyl)-, and 3-(5-tetrazolyl)-chromones, 2-(3-pyridyl) chromones are reported as antiallergic, 7,8 coronaryvasodilatory, [9][10][11] and insecticidal, 7 agents. "Isoxazole penicillins" are reported to be potent antibacterial agents.…”

“…The attachment of a tetrazolyl or pyridyl ring at 2-position of chromones gave compounds with antiallergic, coronaryvasodilatory and insecticidal activity, [7][8][9][10][11] . Therefore it is considered worthwhile to synthesize 4H-1-benzopyran-4-ones with 3, 5-disubstituted isoxazolyl heterocyclic ring attached at C-2 position and study their insect-antifeedant activity against agricultural pest tobacco caterpillar larvae (Spodoptera litura F) in a non-choice laboratory study.…”
