TL;DR: A novel Bi(OTf)3-mediated cycloisomerization of γ-alkynyl arylketones 4, 7, or 10 with molecular sieve in MeNO2 affords 3-substituted furans 3, 8, or 11 at rt for 3 h in moderate to good yields.
74 citations
TL;DR: PdCl 2/CuCl2/NH4OAc-mediated the domino aerobic Wacker-type aminocyclization of α-allyl-β-ketosulfones 4 in cosolvents THF and MeOH via 1,4-sulfonyl migration with moderate to good yields.
68 citations
TL;DR: A straightforward synthesis of (±)-coerulescine and (−)-horsfiline has been established from 3-formyl-3-phenylpyrrolidine employing 4-hydroxypiperidine as the starting material as discussed by the authors.
60 citations
TL;DR: Intramolecular carbonyl allylation of α-prenyl or α-geranyl β-arylketosulfones 5 in the presence of molecule sieves affords substituted benzenes 6-7 in moderate to good yields.
45 citations
TL;DR: In this article, a polysubstituted pyroglutamate carbon skeleton, with three contiguous asymmetric centers, was built up in one step and a ring-closure mechanism was proposed for the reactions.

TL;DR: This review concludes that Etherification without Cyclization and N-Alkylation should be considered as separate science, and the proposed treatment of Etherification with Cyclization as a separate science should be reconsidered.
