internal redox reaction/ringexpansion sequence. The interesting feature of the present system is that it allows for the divergent synthesis of the target skeleton depending on the selected Lewis acid catalyst. When benzylidene malonates with a cyclic structure at the ortho-position were treated with BF3·OEt2, three sequential processes (internal redox reaction/elimination of the alkoxy group/ring expansion)

A new catalyst system for the intramolecular acylation of aldehydes with aryl bromides via C-H functionalization is described. The transformation is distinguished by a remarkable functional group tolerance and hence allows for the synthesis of a wide variety of highly functionalized benzocyclobutenones with a diverse set of substitution patterns from simple and easily accessible precursors.
