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-1,2-divinyl intermediates.
在新型双环砜3-噻二环[3.2.0]庚-6-烯3,3-二氧化物中进行6,7-双键的功能化,然后热挤出SO 2,可以直接进入七元环通过产生的顺式-1,2-二乙烯基中间体的Cope重排来合成系统。
