Benzofurans or isochromenes via the ring-opening cyclization of cyclopropene derivatives with organolithiums
Liu, Yu,Ma, Shengming
supporting information; experimental part, p. 720 - 723 (2012/04/17)
A new and efficient approach to benzocycles from cyclopropene derivatives is described. Deprotection by organolithiums and subsequent ring-opening cyclization of the related 2-cyclopropenyl phenyl or benzyl acetates generated benzofurans and isochromenes in one pot.
Chemistry of aminophenols. Part 3: First synthesis of nitrobenzo[b]furans via a coupling-cyclization approach
Dai, Wei-Min,Lai, Kwong Wah
, p. 9377 - 9380 (2007/10/03)
The first synthesis of 4-, 5-, and 6-nitrobenzo[b]furans has been achieved via the Sonogashira cross-coupling reaction of 2-iodonitrophenol acetates prepared from commercially available and inexpensive 2-aminonitrophenols. The obtained 2-alkynylnitropheno
