A straightforward formation of six- and eight-membered rings via the radical cyclization of specifically designed ynamides is reported. This strategy provides a protoberberine analog in only three steps by a radical cyclization cascade.
据报道,通过专门设计的酰胺类化合物的自由基环化反应,可直接形成六元和八元环。通过自由基环化级联,该策略仅需三步即可提供原小to碱类似物。
