Mann, Inderjit S. published the artcileTransition metal-mediated synthesis of some prenylated phytoalexins of Morus alba Linn, Category: benzofurans, the main research area is moracin prenylated; resorcinylbenzofuran; benzofuran resorcinyl; coupling stannylbenzofuran iodoresorcinol chromium carbonyl.
Directed functionalization of resorcinol and benzofuran rings was achieved by activation with a coordinated tricarbonylchromium(0) unit and vicinal or remote lithiation directed by methoxy or tert-butyldiphenylsilyloxy groups resp. The process was applied either before [to the geranylbenzofuran for mulberrofuran B (I, R = Me, R1 = geranyl, R2-R4 = H)] or after [for moracin C (I, R-R2 = H, R3 = prenyl, R4 = Me)] Pd-catalyzed coupling of the 2-stannylated benzofuran and the 5-iodinated resorcinol moieties. In addition moracin I (I, R, R1, R3 = H, R2 = prenyl, R4 = Me) was synthesized by a Stille coupling of the stannylated benzofuran with the phloroglucinol triflate. Application to the synthesis of albafuran A (I, R, R1, R3, R4 = H, R2 = geranyl) gave, unexpectedly, the 3-geranylbenzofuran II.
Tetrahedron published new progress about Coupling reaction. 50551-63-8 belongs to class benzofurans, name is 6-Methoxybenzofuran, and the molecular formula is C9H8O2, Category: benzofurans.
