Distribution of Catalytic Species as an Indicator to Overcome Reproducibility Problems
Companyó, Xavier,Burés, Jordi
, p. 8432 - 8435 (2017)
Irreproducibility is a common issue in catalysis. The ordinary way to minimize it is by ensuring enhanced control over the factors that affect the reaction. When control is insufficient, some parameters can be used as indicators of the reaction performanc
A comparison of the benzylic and the allylic group as a donor in the formal [4+2] cycloaddition to tetrahydropyrans using donor-acceptor cyclobutanes
Ahmed, Awais,Christie, Steven D.R.,Pritchard, Gareth J.
, p. 3028 - 3031 (2017)
The allyl group was shown to be preferred over the benzyl group as a donor in the formal [4+2]-cycloaddition reaction between a donor-acceptor cyclobutane and various aldehydes to give tetrahydropyrans.
Highly Diastereo- and Enantioselective Cascade Synthesis of Bicyclic Lactams in One-Pot
Jiang, Yan,Deiana, Luca,Alimohammadzadeh, Rana,Liu, Leifeng,Sun, Junliang,Córdova, Armando
, p. 1158 - 1164 (2018)
A versatile and highly stereoselective synthetic route to functionalized bi- and tricyclic lactams (up to > 20:1 dr and 99 % ee) in one pot from simple starting materials (allylic alcohols, enals, diamines and amino alcohols) using cascade transformations promoted by chiral amine/Br?nsted or metal/chiral amine/Br?nsted relay catalysis is disclosed. Here molecular oxygen is employed as the terminal oxidant for the latter relay catalysis approach.
A Recyclable Chiral 2-(Triphenylmethyl)pyrrolidine Organocatalyst Anchored to [60]Fullerene
Rosso, Cristian,Emma, Marco G.,Martinelli, Ada,Lombardo, Marco,Quintavalla, Arianna,Trombini, Claudio,Syrgiannis, Zois,Prato, Maurizio
, p. 2936 - 2944 (2019/04/26)
Hybridization of a chiral 3-hydroxy-2-trityl-pyrrolidine deriving from (R)-pyrrolidinol with [60]fullerene via click chemistry provides a highly efficient supported enantioselective organocatalyst, which was successfully exploited in a Michael addition of
Polystyrene-supported diarylprolinol ethers as highly efficient organocatalysts for Michael-type reactions
Alza, Esther,Sayalero, Sonia,Kasaplar, Pinar,Almasi, Diana,Pericas, Miquel A.
supporting information; experimental part, p. 11585 - 11595 (2011/11/29)
α,α-Diphenylprolinol methyl- and trimethylsilyl ethers anchored onto a polystyrene resin have been prepared by a copper-catalyzed azide-alkyne cycloadditions (CuAAC). The catalytic activity and enantioselectivity displayed by the O-trimethylsilyl derivati
The Michael Addition of Dimethyl Malonate to α,β-Unsaturated Aldehydes Catalysed by Proline Lithium Salt
Yamaguchi, Masahiko,Yokota, Naoyuki,Minami, Toru
, p. 1088 - 1089 (2007/10/02)
In the presence of 10 molpercent of proline lithium salt, Michael adducts were obtained from dimethyl malonate and α,β-unsaturated aldehydes in high yield.
