In the present study, the gold(I)-catalyzed reaction of 1,5-allenenes was controlled in such a way that instead of a [2+3] cycloaddition, a 5-exo-cyclization with the formation of a carbocation occurred. The latter could be trapped with both oxygen and carbon nucleophiles. In the investigated system, fused tricyclic frameworks I (R = Me; R1 = Me, Cl, Br, etc.; Nu = OMe, OEt, 2-furyl, etc.) with three contiguous stereocenters with excellent chemo- and diastereoselectivity in up to 95% yield were obtained.
