Dimethyldioxirane epoxidation of 6,6-disubstituted fulvenes
Adam,Hadjiarapoglou,Meffert
, p. 6697 - 6700 (2007/10/02)
The endocyclic bis-epoxides of various pentafulvenes were readily prepared by epoxidation with excess dimethyldioxirane; stoichiometric epoxidation yielded mixtures of the bis-epoxides and the labile monoepoxides, but no exocyclic epoxides were observed.
