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 1H-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 KBrO3 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 NaBH4 and NiCl2.6H2O in methanol solvent in mild condition. Based on FT-IR, GC-MS and 1H-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.
