Synthesis of Cycloproparenes from Furans: 2,7-Diphenyl-1H-cyclopropa[b]-naphthalene

2,7-Diphenyl-1H-cyclopropa[b]naphthalene (1b) is synthesized in 72% overall yield via cycloaddition of 1,3-diphenylisobenzofuran (2b) to 1-bromo-2-chlorocyclopropene (3a) followed by aromatization of the adduct 4b with low-valent titanium.
