Zhang, Pingping,Zhang, Wuchang,Zhang, Tingfang,Wang, Zhiqin,Zhou, Wenjuan
, p. 491 - 492 (1991)
The mechanism of Pd-catalysed reaction of allylic acetates with carbonyl compounds in the presence of zinc chloride via electroreduction is reported.
New computational and experimental evidence for the mechanism of the Sakurai reaction
Bottoni, Andrea,Costa, Anna Luisa,Di Tommaso, Donata,Rossi, Ivan,Tagliavini, Emilio
, p. 12131 - 12135 (1997)
Reaction of aldehydes with allyltrimethylsilane promoted by BF3 (Sakurai reaction) affords fluorotrimethylsilane and a borylated homoallylic alcohol in a noncatalytic fashion. These reaction products have been identified through 13C
Synthesis of 4-aminotetrahydropyran scaffolds for drug discovery
Nortcliffe, Andrew,Milne, Gavin D.S.,Hamza, Daniel,Moody, Christopher J.
, p. 2218 - 2225 (2017)
Functionalised tetrahydropyran scaffolds were prepared using a tethered enol-ether Prins cyclisation and elaborated to show their potential use in library synthesis. The key 4-hydroxytetrahydropyran scaffold could be readily manipulated to the 4-azidotetr
Preparation of active zinc by reduction of zinc chloride with sodium in liquid ammonia and its use in the Barbier reaction
Makosza, Mieczysaw,Grela, Karol
, p. 9225 - 9226 (1995)
Active zinc powder produced by reduction of anhydrous zinc chloride with solution of sodium in liquid ammonia exhibits high reactivity in the Barbier type reaction both in THF and liquid ammonia solution.
Synthesis of a new C2-symmetric chirat diol: Application to asymmetric allylboration.
Mears, Richard J.,De Silva, Harshani,Whiting, Andrew
, p. 17395 - 17406 (1997)
New C2-symmetric chiral diol 1b was prepared from diol 3a, by a thionyl chloride mediated double elimination, hydrogenation and deprotection sequence. A comparative study of the asymmetric allylboration of benzaldehyde with the allylboronates 1
Reaction Pathway and Transition State of the Zn-Promoted Barbier-Type Reactions of Benzaldehyde and Benzophenone with Allylic Iodides
Yamataka, Hiroshi,Nishikawa, Kazuyoshi,Hanafusa, Terukiyo
, p. 242 - 245 (1994)
The carbonyl-14C kinetic isotope effects and the substituent effects on the reactivity of the Zn-promoted Barbier-type reaction of allyl iodide (3-iodo-1-propene) with benzaldehyde and benzophenone were determined in THF at 25 deg C.The observed normal ca
Simultaneous coordination and double activation phenomena of carbonyl and epoxy oxygen by bis-titanium reagent as a bidentate lewis acid catalyst
Asao, Naoki,Kii, Satoshi,Hanawa, Hideo,Maruoka, Keiji
, p. 3729 - 3732 (1998)
The new bidentate Ti catalyst, (anthraquinone-1,8- dioxy)bis(triisopropoxy-titanium) (1) can be successfully designed and utilized for the simultaneous coordination to carbonyl substrates. The high double-activation ability of the bidentate Ti catalyst 1 toward carbonyls is emphasized using several synthetic examples in comparison with the corresponding monodentate Ti catalyst. The intermediary coordination complex formation of bidentate 1 with DMF or epoxycyclohexane as a carbonyl or epoxy substrate is characterized by 13C NMR spectroscopy.
Chemoselective RuO4 oxidation of phenyl or p-methoxyphenyl groups to carboxylic acid functions in the presence of a tetrahydropyran ring
Miranda,Vasconcellos
, p. 1767 - 1770 (2004)
We describe the first example of a chemoselective oxidation of phenyl and p-methoxyphenyl groups to carboxylic acid functions in the presence of a tetrahydropyran ring, using 0.02 mol% of RuCl3 and a co-oxidant. The use of NaIO4 as c
Isostructural mesoporous ionic crystals as a tunable platform for acid catalysis
Kikukawa, Yuji,Kitao, Takashi,Ogiwara, Naoki,Shimoyama, Yuto,Uchida, Sayaka,Weng, Zhewei
, p. 10328 - 10333 (2020)
Eleven isostructural mesoporous ionic crystals (meso-PICs) are synthesized. The initial activities of the Barbier-Grignard reaction, which is a typical C-C bond formation reaction, catalyzed by the meso-PICs are dependent on the acid dissociation constant
Structure-activity relationship of formamides as organocatalysts: The significance of formamide structure and conformation
Nguyen, Dieu,Akhani, Ravish K.,Sheppard, Cody I.,Wiskur, Sheryl L.
, p. 2279 - 2283 (2013)
The impact of the structure and conformation of formamides as organocatalysts was investigated and reported herein as a structure-activity relationship. Selected formamides and some amides were evaluated for their ability to activate allyltrichlorosilane
