Applicazioni

3-Bromofuran was a synthesis reagent used in the preparation of 2-substituted 3-furfurals. It was also used in the synthesis of 5,6-dehydronorcantharidins. It is one of the volatile metabolites discussed in studies for detecting and discriminating diseases of onion.

Note

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from heat, oxidizing agents.

Precursor of 3-lithiofuran by treatment with n-BuLi at low temperatures. Isomerization to 2-lithiofuran tends to occur above -40o: Tetrahedron, 46, 1199 (1990). With LDA at -78o, selective 2-lithiation can be achieved to give 3-bromo-2-lithiofuran, which has been used in synthesis of phenethylthiazolylthiourea (PETT) analogues as potential HIV-1 reverse transcriptase inhibitors: J. Med. Chem., 39, 4261 (1996).
