Ring-opening iodination or bromination of unstrained cycloalkanols with NaI or NaBr and PhI(OAc)2 under visible light irradiation is developed. In this protocol the concentration of I2is modulated through the generation of triiodide (I3-), thus significantly avoiding undesired side reactions. The reaction is under mild conditions and has a wide substrate scope, thus providing a practically useful method for accessing ω-iodo or ω-bromoketones.

Described herein is a novel, useful, visible light-promoted ring-opening functionalization of unstrained cycloalkanols. Upon scission of an inert cyclic C-C σ-bond, a set of medium- and large-sized rings are readily brominated under mild reaction conditio
A NEW ROUTE TO γ-SUBSTITUTED γ-LACTONES AND δ-SUBSTITUTED δ-LACTONES BASED ON THE REGIOSELECTIVE β-SCISSION OF ALKOXY RADICALS GENERATED FROM TRANSANNULAR HEMIACETALS

A new general synthesis of γ-substituted γ-lactones and δ-substituted δ-lactones including dihydro-5-octyl-2(3H)-furanone, a natural pheromone, is described.The synthesis involves the regioselective β-scission of alkoxy radicals generated from transannular hemiacetals as the key step. Key Words: γ-Lactones; δ-Lactones; Mercury(II) Oxide-Iodine Reagent; Photolysis; β-Scission of Alkoxyl Radicals
