Masuyama, Yoshiro,Marukawa, Masanori
, p. 5963 - 5965 (2007)
3-Alkoxypropenes, namely allyl ethers such as allyl butyl ether, allyl 2-hydroxypropyl ether, and diallyl ether, serve as reagents for the allylation of aldehydes with tin(II) chloride in the presence of a catalytic amount of [IrCl(cod)]2 in TH
Polymer-supported formamides as reusable organocatalysts for allylation of aldehydes with allyltrichlorosilane
Ogawa, Chikako,Sugiura, Masaharu,Kobayashi, Shu
, p. 192 - 193 (2003)
New types of polymer-supported formamides have been synthesized from chloromethylated resins and formamides; it was found that the polymers worked well as organocatalysts in the allylation of aldehydes with allyltrichlorosilane to afford homoallylic alcoh
Gallium metal mediated allylation of carbonyl compounds and imines under solvent-free conditions
Andrews, Philip C.,Peatt, Anna C.,Raston, Colin L.
, p. 243 - 248 (2004)
Gallium metal is effective in mediating the allylation of various carbonyl compounds and imines under solvent-free conditions, with the application of sonic energy, affording the corresponding homoallylic alcohols and amines. The imines themselves were al
AN EFFICIENT SYNTHESIS OF HOMOALLYL ALCOHOLS BY THE REACTION OF ALLYL HALIDES WITH CARBONYL COMPOUNDS IN THE PRESENCE OF METALLIC TIN
Mukaiyama, Teruaki,Harada, Taira
, p. 1527 - 1528 (1981)
In the presence of metallic tin, allyl halides were found to react smoothly with carbonyl compounds under mild conditions to give the corresponding homoallyl alcohols in good yields.
Additive effects of ligand activated allylation of aldehydes by allyltrichlorosilane
Short, Joanne D.,Attenoux, Sandrine,Berrisford, David J.
, p. 2351 - 2354 (1997)
The rate of allylation of aldehydes using a combination of allyltrichlorosilane and O-donor ligands can he profoundly accelerated by the addition of a range of simple tetra-n-butylammonium salts. Measured tin values decrease from over 6 hours under define
Ruthenium complex catalyzed allylation of aldehydes with allylic acetates
Tsuji, Yasushi,Mukai, Takeshi,Kondo, Teruyuki,Watanabe, Yoshihisa
, p. C51 - C62 (1989)
Ruthenium complexes such as Ru3(CO)12 and RuCl3.nH2O show high catalytic activity in the allylation of aldehydes by allylic acetates at 120 deg C to give homoallylic alcohols in good yields.
Ni-Catalyzed 1,2-Diarylation of Alkenyl Ketones: A Comparative Study of Carbonyl-Directed Reaction Systems

A nickel-catalyzed 1,2-diarylation of alkenyl ketones with aryl iodides and arylboronic esters is reported. Ketones with a variety of substituents serve as effective directing groups, offering high levels of regiocontrol. A representative product is diversified into a wide range of useful products that are not readily accessible via existing 1,2-diarylation reactions. Preliminary mechanistic studies shed light on the binding mode of the substrate, and Hammett analysis reveals the effect of electronic factors on initial rates.
3,3′-Bithiophene-Based Chiral Bisphosphine Oxides as Organocatalysts in Silicon-Derived Lewis Acid Mediated Reactions
Benaglia, Maurizio,Benincori, Tiziana,Raimondi, Laura Maria,Rossi, Sergio
, p. 535 - 546 (2020/03/27)
This account summarizes the development of new biheteroaromatic chiral bisphosphine oxides. 3,3′-Bithiophene-based phosphine oxides (BITIOPOs) have been successfully used as organocatalysts to promote Lewis base catalyzed, Lewis acid mediated stereoselective transformations. These highly electron-rich compounds, in combination with trichorosilyl derivatives (allyltrichlorosilane and silicon tetrachloride), generate hypervalent silicon species that act as chiral Lewis acids in highly diastereo- and enantioselective organic reactions. Several relevant examples related to these applications are discussed in detail. 1 Introduction 2 The BITIOPO Family 3 Enantioselective Opening of Epoxides 4 Enantioselective Allylation of Aldehydes 5 Stereoselective Direct (Double) Aldol-Type Reaction with Ketones 6 Stereoselective Direct Aldol-Type Reaction with Ester Derivatives 7 Conclusions.
Bi(cyclopentyl)diol-Derived Boronates in Highly Enantioselective Chiral Phosphoric Acid-Catalyzed Allylation, Propargylation, and Crotylation of Aldehydes
Yuan, Jinping,Jain, Pankaj,Antilla, Jon C.
, p. 12988 - 13003 (2020/11/23)
In this study, we disclose the catalytic addition of bi(cyclopentyl)diol-derived boronates to aldehydes promoted by chiral phosphoric acids, allowing for the formation of enantioenriched homoallylic, propargylic, and crotylic alcohols (up to >99% enantiom
Axially chiral N,N′-dioxides ethers for catalysis in enantioselective allylation of aldehydes
Wu, Shijie,Xing, Yongfei,Wang, Jie,Guo, Xingchen,Zhu, Huajie,Li, Wan
supporting information, p. 947 - 957 (2019/08/30)
A series of axially chiral ethers synthesized from biscarboline N,N′-dioxides, (S)-1a to (S)-1n, was investigated in enantioselectivity addition reactions of allyltrichlorosilane with a series of substituted aldehydes, including bulky substituted aldehydes. High enantioselectivities (up to 96%ee) were achieved using the catalyst (S)-1k at 1 mol % loading.
