Observations on the intramolecular palladium(0) catalysed [3 + 2] cycloaddition of diphenylmethylenecyclopropanes
Abstract
The intramolecular variant of the palladium(0) catalysed cycloaddition of diphenylmethylenecyclopropanes with olefinic and acetylenic acceptors provides a regiocontrolled route to highly functionalised bicyclo[3.3.0]octane derivatives.
