“…The usage of some isatin derivatives for antibacterial, antimalarial, antiproliferative and anti-coagulant [4][5][6][7][8][9], antimicrobial, anticonvulsative, anticancer, antiHIV, etc. activities and also antifungal, herbicidal agents [10][11][12][13][14][15][16][17].Many other remarkable applications are reported in the literature, such as the selective inhibition of corrosion in mild steel by 5- [18,19]. These 5-Chloroisatin derivatives were synthesized using Nalkylation reaction under catalysis by phase transfer [20][21][22][23].…”
