Facile carbolithiation of bent alkyne without catalyst. Tandem route to dibenzo[b, f]pentalenes from dibenzocyclooctadiyne

Babu, Govindarajulu,Orita, Akihiro,Otera, Junzo

, p. 1296 - 1297 (2008)

Nucleophilic addition of RLi to a triple bond of dibenzocy-cloocta[a, e]diyne provides dibenzo[b, f]pentalene motif through trans-annulation of the resulting vinyllithium. Dibenzopentalene anion thus formed reacts with various electrophiles such as aldehydes, alkyl halides, acid halide, and Me 3SiCl to give the corresponding products. Copyright
