Wang, Wentao,Gou, Shaohua,Liu, Xiaohua,Feng, Xiaoming
, p. 2875 - 2878 (2007)
A new self-assembled titanium catalyst system has been developed for the asymmetric cyanoethoxycarbonylation of aldehydes which produced the desired products in moderate to excellent yields (up to 99%) with high enantioselectivities (up to 94% ee) under m
Asymmetric cyanoethoxycarbonylation of aldehydes catalyzed by heterobimetallic aluminum lithium bis(binaphthoxide) and cinchonine

, p. 343 - 349 (2007)
Highly efficient catalytic asymmetric cyanoethoxycarbonylation of aldehydes was achieved by 10 mol% cinchonine with 10 mol% heterometallic (S)-aluminum lithium bis(binaphthoxide), which gave the cyanohydrins ethyl carbonates in excellent isolated yields (

(Equation presented) The bimetallic titanium complex [(salen)TiO] 2, where salen is the ligand derived from (R,R)-cyclohexanediamine and 3,5-di-tert-butyl-salicylaldehyde, has been shown to catalyze the asymmetric addition of ethyl cyanoformate
Tuning the Catalytic Activity of Tertiary-Amine Functionalized Polyacrylonitrile Fibers by Adjusting the Surface Microenvironment
Li, Pengyu,Liu, Yuanyuan,Cao, Jian,Tao, Minli,Zhang, Wenqin
, p. 3725 - 3732 (2017)
Polyacrylonitrile fibers were functionalized with different amines to construct special tridimensional catalytic microenvironments at the surface. The polarity of the microenvironments at the surface of the fiber catalyst was tuned by changing the ratio o
Highly enantioselective cyanation of aldehydes catalyzed by a multicomponent titanium complex
Gou, Shaohua,Chen, Xiaohong,Xiong, Yan,Feng, Xiaoming
, p. 5732 - 5736 (2006)
A new multicomponent bifunctional catalytic system based on a titanium complex was used for the efficient enantioselective cyanation of aldehydes. The catalyst was readily prepared from tetraisopropyl titanate (Ti(Oi-Pr) 4), (S)-6,6′-dibromo-1,
Highly enantioselective cyanoformylation of aldehydes catalyzed by a mononuclear salen-Ti(OiPr)4 complex produced in situ
Chen, Shi-Kui,Peng, Dan,Zhou, Hui,Wang, Li-Wei,Chen, Fu-Xue,Feng, Xiao-Ming
, p. 639 - 644 (2007)
An efficient enantioselective cyanoformylation of aldehydes with ethyl cyanoformate, catalyzed by a salen-Ti(OiPr)4 complex generated in situ, has been developed. Studies of non-linear effects indicated that the mononuclear salen-titanium compl
Kinetics and mechanism of base catalysed ethyl cyanoformate addition to aldehydes Dedicated to the memory of Professor Sandy McKillop
North, Michael,Urwin, Stephanie
, p. 7100 - 7105 (2014)
The mechanism by which tertiary amines catalyse the formation of cyanohydrin carbonates from aldehydes and alkyl cyanoformates is investigated by means of a kinetic study. The reaction rate shows a second order dependence on amine concentration unless the
Asymmetric cyano-ethoxycarbonylation of aldehydes catalyzed by self-assembled titanium catalyst
Gou, Shaohua,Liu, Xiaohua,Zhou, Xin,Feng, Xiaoming
, p. 7935 - 7941 (2007)
A new self-assembled catalyst based on titanium complex has been developed for the effective enantioselective cyano-ethoxycarbonylation of aldehydes. The self-assembled catalyst was readily prepared from (R)-3,3′-bis((methyl((S)-1-phenylethyl)amino)methyl
Consecutive reactions to construct tricarbonyl compounds and synthetic applications thereof
Madro?ero, Diego,Mujica-Martinez, Cesar A.,Vázquez, Alfredo
, p. 33235 - 33244 (2021/12/09)
Lithium anions derived from O-carbonate-protected cyanohydrins undergo conjugate addition to cycloalkenones with the concomitant transfer of the alkoxycarbonyl group to produce tricarbonyl compounds. These products offer numerous possibilities for further
