A vinyl/α‐oxo carbene is generated via an α‐oxo carbene formation and subsequently transferred across the second alkyne. These highly active species can react with nitriles in an intermolecular fashion to provide substituted oxazoles. This methodology goes through 1,6‐carbene shift and offers a range of valuable products.
乙烯基/ α -氧代碳烯生成经由一个α -氧代碳烯的形成和随后穿过第二炔传送。这些高活性物质可以分子间的方式与腈反应,以提供取代的恶唑。该方法论经过1,6-卡宾的转变,并提供了一系列有价值的产品。
