Organocatalytic asymmetric aldol reactions mediated by a cysteine-derived prolinamide
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
In this Letter, a cysteine-derived prolinamide is described to act as a robust and effective organocatalyst for enantioselective aldol reactions. (c) 2008 Elsevier Ltd. All rights reserved.
Naturally occurring alfa-hydroxy acids: Useful organocatalysts for the acetylation of cellulose nanofibres
(Bentham Science Publishers, 2016-03)
Cellulose nanoribbons obtained from bacterial fermentation have been esterified by means of a solventless organocatalytic route. The esterification methodology involves acetic anhydride as acylant and three different ...
A Hydrogen Bond Rationale for the Enantioselective beta-Alkenylboration of Enones Catalyzed by O-Monoacyltartaric Acids
(American Chemical Society, 2014-06)
DFT calculations suggest that O-monoacyl L-tartaric acids catalyze the asymmetric conjugate alkenylboration of enones through transition structures that are stabilized by hydrogen-bonding interactions. Formation of a ...
Organocatalytic acetylation of starch: Effect of reaction conditions on DS and characterisation of esterified granules
(Elsevier, 2015-03)
Starch acetates with varying degree of substitution (DS) were prepared by a novel solvent-free organocatalytic methodology. The acetylation protocol involved a non-toxic biobased α-hydroxycarboxylic acid as catalyst, and ...
Synthesis of optically active 1,2,3-trisubstituted azetidines employing an organocatalytic approach with L-proline
(Elsevier, 2013-01-30)
A concise organocatalytic approach towards optically active 1,2,3-trisubstituted azetidines, including a study of the scope and limitations of the synthetic sequence, is reported. The synthesis comprises the one-pot ...
Surface esterification of cellulose nanofibers by simple organocatalytic methodology
(Elsevier, 2014-08)
Bacterial cellulose nanofibers were esterified with two short carboxylic acids by means of a simpleand novel organic acid-catalyzed route. The methodology proposed relayed on the use of a non-toxicbiobased -hydroxycarboxylic ...
