Medium and Large N-Heterocycle Formation via Allene Hydroamination with a Bimetallic Rh(II) Catalyst
Bohman, Benjamin O.,Davis, Rhen C.,Forson, Kelton G.,McKnight, Caitlyn E.,Michaelis, David J.,Owens, Rachel N.,Smith, Stacey J.,Stillwell, Lillian R.,Wayment, Coriantumr Z.

We report the synthesis of a 2-phosphinoimidazole-derived bimetallic Rh(II) complex that enables intramolecular allene hydroamination to form 7- to 10-member rings in high yield. Monometallic Rh complexes, in contrast, fail to achieve any product formatio
Allene-based Electrophile-mediated Cyclisations: Efficient Synthesis of Medium Ring Azacycles
Shaw, Robert W.,Gallagher, Timothy
, p. 3549 - 3556 (2007/10/02)
While AgI- and PdII-based electrophiles have limited application in cyclisation of allenic amines leading to 7-membered and larger azacycles, these rings may be obtained using iodine as the electrophilic trigger.Iodination of the N-b

PdII-mediated cyclisation and methoxycarbonylation of the phenyl-substituted allenic sulfonamides 4, 5 and 6 gave the corresponding N-sulfonyl 2,3-, 2,4- and 2,5-disubstituted pyrrolidines 9, 10 and 11, respectively.With the exception of compou

Application of Electrophile-mediated Cyclisations to the Synthesis of the Hexahydroazepine Ring System
Shaw, Robert,Lathbury, David,Anderson, Martin,Gallagher, Timothy
, p. 659 - 660 (2007/10/02)
Allenic oxime 6 undergoes efficient AgI-catalysed cyclisation to give the hexahydroazepine-based nitrone 7; this reactive 1,3-dipole was subsequently trapped by styrene and N-methylmaleimide to give the adducts 8 and 9 respectively.
