Its mono bromo and tribromo derivatives were synthesized. Two more derivatives were synthesized by acylation. Compound 1 (3.6,8-tribromo-7-hydroxy-4-methyl-chromen-2-one) was found to be the most potent against IV(th) instar larvae of C. quinquefasciatus and A. aegypti the LC(50) being 1.49 and 2.23 ppm respectively. It showed 100% larval mortality at 25 ppm against A. aegypti and at 10 ppm against C. quinquefasciatus. Compounds 1 and 2 (3,6,8-tribromo-7-hydroxy-4-methyl-chromen-2'-oxo-2H-chromen-7-yl acetate) showed remarkable ovicidal activity. Significant reduction of 80-85%, hatching of eggs of both mosquito species was observed at the highest dose of 100 ppm. The hatched larvae showed 100% mortality in the successive instars. Compounds 3 and 4 (3-bromo-7-hydroxy-4-methyl-chromen-2-one and 3-bromo-4-methyl-2'-oxo-2H-chromen-7-yl acetate) showed moderate activity against both mosquito species.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">11</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Indiain</style></custom3><custom4><style face="normal" font="default" size="100%">1.165</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Chandrachood, Pranav S.</style></author><author><style face="normal" font="default" size="100%">Jadhav, Amol R.</style></author><author><style face="normal" font="default" size="100%">Garud, Dinesh R.</style></author><author><style face="normal" font="default" size="100%">Deshpande, Nirmala R.</style></author><author><style face="normal" font="default" size="100%">Puranik, Vedavati G.</style></author><author><style face="normal" font="default" size="100%">Kashalkar, Rajashree V.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Efficient method for the synthesis of quinoxaline derivatives catalyzed by titanium silicate-1</style></title><secondary-title><style face="normal" font="default" size="100%">Research on Chemical Intermediates</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">2-Diketones</style></keyword><keyword><style  face="normal" font="default" size="100%">Aromatic 1</style></keyword><keyword><style  face="normal" font="default" size="100%">o-Phenylenediamine</style></keyword><keyword><style  face="normal" font="default" size="100%">Quinoxaline</style></keyword><keyword><style  face="normal" font="default" size="100%">Room temperature</style></keyword><keyword><style  face="normal" font="default" size="100%">Titanium silicate-1</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">DEC</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">46</style></volume><pages><style face="normal" font="default" size="100%">5219-5230</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;A series of quinoxaline derivatives were efficiently synthesized by convenient and simple procedure in excellent yields using 1 wt.% of titanium silicate (TS-1) catalyzed reaction of 1,2-diamines and 1,2-diketones in methanol at room temperature.
