Hydroazulenones and hydroazulenediones are prepared efficiently from bicyclo[3.3.0]octanones via two carbon annulation utilizing thermal [2+2] cycloaddition of dichloroketene and fluoride or chloride induced fragmentation of the cycloadduct.
由双环[3.3.0]辛烷酮通过二碳烯酮的热[2 + 2]环加成反应和氟化物或氯化物引起的环加成物的裂解,通过两次碳成环反应,可以高效地制备双环[3.3.0]辛酮和双氢酮。
