The scope for tandem radical mediated macrocyclisation-transannulation processes (Scheme 1) in the elaboration of polycycles is illustrated with the facile syntheses of linear 5,6-, 6,6- and 5,7-ring fused carbobicycles, viz7, 8, 11, 13 from appropriate iododienone precursors, viz1, 2, 12 on treatment with Bu3SnH-AIBN.
精细合成线性的5,6-,6,6-和5,7环稠合碳环说明了串联多环化过程中串联自由基介导的大环化-环转移过程(方案1)的范围,即7、8, 11,13从适当的前体iododienone,即1,2,12与治疗卜3 SNH-AIBN。
