Autor: Elisa De Marchi, Davide Arnodo, Elia Maffeis, Dina Scarpi, Cristina Prandi, Ernesto G. Occhiato
Publikováno v: SynOpen, Vol 05, Iss 02, Pp 145-151 (2021)
The synthesis of both enantiomers of a key intermediate in the synthesis of halofuginone was accomplished by a Candida antarctica lipase B (CAL-B)-catalyzed kinetic resolution of the corresponding racemate. When the resolution was carried out in the

Pentannulation of N-heterocycles by a tandem gold-catalyzed [3,3]-rearrangement/Nazarov reaction of propargyl ester derivatives: a computational study on the crucial role of the nitrogen atom
Autor: Giovanna Zanella, Martina Petrović, Dina Scarpi, Ernesto G. Occhiato, Enrique Gómez-Bengoa
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 16, Iss 1, Pp 3059-3068 (2020)
The tandem gold(I)-catalyzed rearrangement/Nazarov reaction of enynyl acetates in which the double bond is embedded in a piperidine ring was computationally and experimentally studied. The theoretical calculations predict that the position of the pro

Gold(I)-Catalyzed Cycloisomerization/Hetero-Diels-Alder Reaction/Ring Opening Cascade to Functionalized Cyclopentadienes
Autor: Dina Scarpi, Francesco Bagni, Cristina Faggi, Asier Carral-Menoyo, Enrique Gómez-Bengoa, Ernesto G. Occhiato
Publikováno v: The Journal of organic chemistry. 87(9)
Six- and seven-membered ring-fused, functionalized cyclopentadienes can be obtained in moderate to excellent yields by a cascade process entailing the Au(I)-catalyzed propargyl Claisen rearrangement/Nazarov cyclization of propargyl vinyl ethers, the

One-Pot Access to 1,7a-Dihydro-1,3a-ethano-indene and 1,8a-Dihydro-1,3a-ethano-azulene Skeletons by a Sequential Gold(I)-Catalyzed Propargyl Claisen Rearrangement/Nazarov Cyclization/[4+2] Cycloaddition Reaction
Autor: Vittoria Langé, Dina Scarpi, Antonia Rinaldi, Ernesto G. Occhiato
Publikováno v: The Journal of Organic Chemistry. 85:5078-5086
An efficient synthetic approach to the tricyclic 1,7a-dihydro-1,3a-ethano-indene and 1,8a-dihydro-1,3a-ethano-azulene skeletons from suitable propargyl vinyl ethers is based on a one-pot, multistep process entailing a gold(I)-catalyzed propargyl Clai
