Nucleophilic attack on the carbonyl group in the tricyclo[2.1.0.02,5]pentan-3-one series leads to straightforward addition or to deep-seated rearrangement depending on the nature of leaving groups six atomic centers removed from the site of reactivity. When the tricyclopentanone nucleus carries two ester groups, stereospecific ring-opening to triethyl -bicyclo[1.1.0]butane-1,2,3-tricarboxylate (II)
对三环[2.1.0.0 2,5 ]戊丹-3-酮系列中羰基的亲核攻击导致直接加成或深度重排,这取决于从反应位点除去的六个原子中心的离去基团的性质。当三环戊酮核带有两个酯基时,会发生三乙基-双环[1.1.0]丁烷-1,2,3-三羧酸酯(II)的立体有择开环。
