- W3019323197 abstract "Synthesis of 4-(5-bromo-4-hydroxyphenyl-3-methoxy)-2-butanone and its potential test as fruit flies attractant has been done. All of products were analyzed by FT-IR GC-MS, and 1 H-NMR. Synthesis of 4-(5-bromo-4-hydroxyphenyl-3-methoxy)-2-butanone was carried out in three steps reaction. First, the bromination of vanillin was performed using KBrO 3 and HBr in acidic condition. Second, aldol condensation of 5-bromovanillin with acetone using base catalyst NaOH 20%. Third, 4-(5-bromo-4-hydroxyphenyl-3-methoxy)-2-butanone was synthesized by reacting the reduction reaction of condensation aldol products with NaBH 4 and NiCl 2 .6H 2 O in methanol solvent in mild condition. Based on FT-IR, GC-MS and 1 H-NMR analyses, the synthesis of 4-(5-bromo-4-hydroxyphenyl-3-methoxy)-2-butanone has been successfully by selective hydrogenation reaction with 68% yield. Testing the result as attractant of fruit fly indicated that synthesized compound can be used as attractant." @default.
