“…Lá, trocou idéias com Arthur C. Cope sobre as recém-descobertas reações transanulares em anéis medianos 35 . O grupo de Prelog havia observado, pela primeira vez, que a reação do trans-ciclodeceno (7) com ácido perfórmico produzia, entre outros produtos, ciclodecano-1,6-diol (8) e 6-hidroxiciclodeceno (9) 36 .…”

“…One mechanism requires loss of a proton from 4 and reprotonation of the resulting orthoquinonoid-type compound 5 (Path "b"), the other proceeds uia a transannular 1,5-hydride shift (10,11) from one of the benzylic positions to the highly reactive cationic center at C-5 (Path "a"); proton loss from 6 would then complete the sequence. In principle, these two mechanisms should be distinguishable by experiments with isotopically labelled substrates.…”
