Wu, Deyan published the artcileTotal synthesis of the 2-(aryl)benzo[b]furan-containing natural products from Artocarpus, COA of Formula: C14H10O4, the publication is Tetrahedron Letters (2015), 56(29), 4383-4387, database is CAplus.
In this study, 2-arylbenzo[b]furan-containing derivatives [i.e., moracin C and moracin M natural products from Artocarpus] have been synthesized in highest overall yield to date (1-7 steps with an overall yield of 41.9%; 4-6 steps with an overall yield of 56.3%). The authors also report the first total synthesis of artoindonesianin B-1 another member of this family, in the same route (8 steps with an overall yield of 11.3%). This discovery provides a concise route for preparing enough amounts of (aryl)benzo[b]furan-containing natural product-like analogs to explore their biol. potential.
