An efficient approach to synthesize naphtho[1,2-b]furan has been developed via platinum-catalyzedtandem reaction. This new tandem catalysis induces a cycloisomerization of allenyl ketone, followed by a 6π-electrocyclization-type reaction of carbene intermediate. The metal carbene proved to be an effective intermediate in the 6π-electrocyclization-type reaction.
通过铂催化串联反应,已经开发了一种合成萘并[1,2- b ]呋喃的有效方法。这种新的串联催化作用引起烯丙基酮的环异构化,然后进行卡宾中间体的6π-电环化型反应。金属卡宾被证明是6π-电环化型反应的有效中间体。
