Synthesis and reactivity of phenyliodonium ylides of benz[b]oxepine-3,5(2H,4H)-diones
摘要:
The reactions of phenyliodonium ylides of cyclic 7-membered beta-diketones bearing two different carbonyl groups with alkynes and nitriles under mild conditions lead to cyclization products and exhibit remarkable regioselectivity. A possible reaction pathway is proposed in order to explain this reactivity.
