Abstract

Abstract Polycyclobutanoid compounds containing an end-fused 3-membered ring are central to the synthesis of the title target molecules: a new mode for their production is presented. Cyclopentadiene 1, 3-diester is isolated and its isomerisation studied. Intermediates supporting the oxygen-walk isomerisation of maleimido-oxepines are isolated.
