We describe a new method for two carbon ring expansions of 5-and 6-membered rings of β-indanone and β-tetralone through the [2+2] photocycloaddition of the enol ethers of the cyclic ketones followed by the radical cleavage of the fused bond of the cyclobutanols derived from the adducts.
我们描述了一种新方法,通过环酮的烯醇醚的 [2+2] 光环加成,接着是稠合的自由基裂解,β-茚满酮和 β-四氢萘酮的 5 和 6 元环的两个碳环扩展。来自加合物的环丁醇的键。
