ChemInform Abstract: Gold(I)-Catalyzed Inter- and Intramolecular Additions of Carbonyl Compounds to Allenenes
Autor: Julien Ceccon, Antonio M. Echavarren, Javier Carreras, Tania Jiménez
Publikováno v: ChemInform. 47
The gold(I)-catalyzed intramolecular reaction of allenes with oxoalkenes leads to bicyclo[6.3.0]undecane ring systems, although in the case of terminally disubstituted allenes, seven-membered rings are formed. The related intermolecular addition of a

Asymmetric [2 + 2] Cycloaddition: Total Synthesis of (−)-Swainsonine and (+)-6-Epicastanospermine
Autor: Andrew E. Greene, Jean-François Poisson, Julien Ceccon
Publikováno v: Organic Letters. 8:4739-4742
[reaction: see text] An asymmetric total synthesis of (-)-swainsonine and (+)-6-epicastanospermine is described from a common intermediate, which is obtained through diastereoselective [2 + 2] cycloaddition of dichloroketene to a chiral enol ether.

Extending the Scope of the [2+2] Cycloaddition of Dichloroketene to Chiral Enol Ethers: Synthesis of (-)-Detoxinine
Autor: Jean-François Poisson, Andrew E. Greene, Julien Ceccon
Publikováno v: Synlett. :1413-1416
Allylic oxidation of a known lactam, obtained by asymmetric [2+2] cycloaddition of dichloroketene to a chiral enol ether, followed by Beckmann ring expansion and dechlorination, affords a potential intermediate for the synthesis of various natural pr

ChemInform Abstract: Access to the Protoilludane Core by Gold-Catalyzed Allene-Vinylcyclopropane Cycloisomerization
Autor: Julien Ceccon, Anthony Pitaval, Antonio M. Echavarren, David Leboeuf
Publikováno v: ChemInform. 45
Gold(I)-catalyzed allene-vinylcyclopropane cycloisomerization leads to the tricyclic framework of the protoilludanes in a single step by a reaction that involves a cyclopropane ring expansion and a Prins cyclization.

Toward the total synthesis of spirastrellolide A. Part 3: Intelligence gathering and preparation of a ring-expanded analogue
Autor: Bernhard Fasching, Alois Fürstner, Gregory W. O'Neil, Cédrickx Godbout, Michaël D. B. Fenster, Julien Ceccon
Publikováno v: Chem. Commun.. :3045-3047
Different methods for the formation of the C.25–C.26 bond of spirastrellolide A (1) are evaluated that might qualify for the end game of the projected total synthesis, with emphasis on metathetic ways to forge the macrocyclic frame.
