Benzofurans or isochromenes via the ring-opening cyclization of cyclopropene derivatives with organolithiums
Liu, Yu,Ma, Shengming
, p. 720 - 723 (2012)
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.
