Enantioselective Palladium-Catalyzed Hydrophosphinylation of Allenes with Phosphine Oxides: Access to Chiral Allylic Phosphine Oxides
Wang, Jun,Yang, Zhiping
supporting information, p. 27288 - 27292 (2021/11/17)
A Pd-catalyzed hydrophosphinylation of alkyl and aryl-oxyallenes with phosphine oxides has been developed for the efficient and rapid construction of a family of chiral allylic phosphine oxides with a diverse range of functional groups. This methodology was further applied in the facile construction of chiral 2H-chromene and later stage functionalization of cholesterol.

, p. 4318 - 4322 (2018/07/29)
A highly regioselective iodosulfonylation of allenes in the presence of CuI and 1,10-phenanthroline has been developed for the synthesis of various useful (E)-α-iodomethyl vinylsulfones in moderate to excellent yields. This practical reaction is fast, operationally simple, and in particular, proceeds under very mild conditions to afford the target products with high regio- and stereoselectivity. The selectivity was illustrated by a conceptual DFT analysis.
Pd-Catalyzed Hydroamination of Alkoxyallenes with Azole Heterocycles: Examples and Mechanistic Proposal
Bernar, Ivan,Fiser, Béla,Blanco-Ania, Daniel,Gómez-Bengoa, Enrique,Rutjes, Floris P. J. T.
supporting information, p. 4211 - 4214 (2017/08/23)
Palladium-catalyzed regio- and enantioselective addition of azole heterocycles to alkoxyallenes was developed (up to 92% yields and up to 94% ee). DFT calculations suggest a new Pd(0)-driven mechanistic pathway proceeding through protonation of the Pd-coo
Gold(I)-Catalyzed Dearomative [2+2]-Cycloaddition of Indoles with Activated Allenes: A Combined Experimental-Computational Study
Ocello, Riccardo,De Nisi, Assunta,Jia, Minqiang,Yang, Qing-Qing,Monari, Magda,Giacinto, Pietro,Bottoni, Andrea,Miscione, Gian Pietro,Bandini, Marco
supporting information, p. 18445 - 18453 (2015/12/24)
The gold-catalyzed synthesis of methylidene 2,3-cyclobutane-indoles is documented through a combined experimental/computational investigation. Besides optimizing the racemic synthesis of the tricyclic indole compounds, the enantioselective variant is pres
Gold(I)-catalyzed hydroindolylation of allenyl ethers
Kona, Chandrababu Naidu,Shinde, Mahesh H.,Ramana, Chepuri V.
supporting information, p. 5358 - 5362 (2015/05/20)
The gold(I)-catalyzed reaction/rearrangement of allenyl ethers has been investigated in the presence of indoles. Either hydroindolylation or alkylation of an indole with the pendant group of allenyl ether has been observed. The reaction outcome seems to b
Site-selective and regioselective Diels-Alder reaction of allenyl aryl ethers
Moghaddam, Firouz Matloubi,Kiamehr, Mostafa
experimental part, p. 1333 - 1337 (2011/09/16)
The site-selectivity and regioselectivity of Diels-Alder reactions of allenyl aryl ethers with cyclopentadiene and acrolein were studied. While cyclopentadiene (as an electron-rich diene) only reacted with the external double bond of allenyl aryl ethers t
Microwave promoted rapid isomerisation of propargyl ethers into allenyl ethers
Moghaddam, Firouz Matloubi,Emami, Rahdar
, p. 4073 - 4077 (2007/10/03)
Aryl or alkyl propargyl ethers have been isomerized efficiently with good to excellent yield into corresponding allenyl ethers in the presence of potassium tert-butoxide under the microwave irradiation.
