摘要

Functionalisation of the 6,7-double bond in the novel bicyclic sulphone, 3-thiabicyclo[3.2.0] hept-6-ene 3,3-dioxide, followed by thermal extrusion of SO2, allows direct entry into seven -membered ring systems via a Cope rearrangement of the resulting cis-I ,2-divinyl intermediates. ... A lack of regio-control in the functionalisation of the central double bond in cis-hexa- I ,3,5-triene frustrates what is con- ceptually an attractive and potentially general ...
