论文部分内容阅读

We have previously used flash vacuum pyrolysis (FVP) of suitably designed stabilised phosphonium ylides to access a range of fused-ring heterocycles via cascade reactions.[1-4]This has now been extended to synthesis of protected benzopyranones as illustrated by conversion of 1 into 2.[5] Further transformations of this toward products such as 3 and extension of the reaction to related examples will also be discussed.
