Facile access to 4-aryl-2(5H)-furanones by Suzuki cross coupling: efficient synthesis of rubrolides C and E was written by Boukouvalas, John;Lachance, Nicolas;Ouellet, Michel;Trudeau, Martin. And the article was included in Tetrahedron Letters in 1998.Recommanded Product: 3,5-Dibromo-4-methoxybenzaldehyde This article mentions the following:
The Pd(0)-catalyzed cross coupling between 4-bromo-2(5H)-furanones and arylboronic acids provides the corresponding 4-aryl-2(5H)-furanones in yields of 61-85%. By using this method in conjunction with furanolate chem., the marine antibiotics rubrolides C (I; X = Br) and E (I; X = H) were synthesized in highly efficient fashion (4 steps, 61 and 56% overall yield, resp.) from β-tetronic acid. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1Recommanded Product: 3,5-Dibromo-4-methoxybenzaldehyde).
3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Recommanded Product: 3,5-Dibromo-4-methoxybenzaldehyde
