An approach to the synthesis of naphtho[b]furans from allyl bromonaphthyl ethers employing sequential photoinduced radical cyclization and dehydrohalogenation reactions
A simple method has been developed for the efficient synthesis of naphtho[b]furans from allyl bromonaphthyl ethers. The approach utilizes a novel photochemical process involving sequential radicalcyclization and dehydrohalogenation. Because light is a readily available, environmentally friendly reagent that produces no by-products, the new process serves as a green synthetic method.
已经开发了一种从烯丙基溴萘基醚有效合成萘并[ b ]呋喃的简单方法。该方法利用了涉及顺序自由基环化和脱卤化氢的新型光化学过程。由于光是一种容易获得的,不产生副产物的环保试剂,因此新工艺可作为绿色合成方法。

Diazaphospholene radical chemistry has been made catalytic with a combination of carbonates and phenylsilane as a terminal reductant. The system is suitable for generation of aryl radicals and intermolecular and intramolecular addition of these radicals.
