Annulation of propargylic dithioacetals leading to furan-containing oligoaryls
Abstract:
Reaction of propargylic dithioacetals with BuLi followed by treatment with dialdehydes yields the corresponding allenyl carbinols which can be cyclized to give the 2,3,5‑trisubstituted furans. The use of this strategy for the synthesis of a range of alternating benzene-furan oligoaryls is described.
