| Research Abstract |
Oxylactonization of ortho-alkenylbenzoates with hypervalent iodine reagent selectively gave 4-oxyisochroman-1-one products. High level of enantioselectivity was achieved using a lactate-based hypervalent iodine reagent for the oxylactonization. In order to demonstrate the expediency of hypervalent iodine-mediated oxylactonization as a unique synthetic strategy, here we disclose a concise entry to 4-oxyisochroman-1-one polyketide metabolites, containing monocerin derivatives and a fusarentin-related natural product.
