Lipase-catalysed deacetylation of androstane and pregnane derivatives: Influence of ring D substitution
(Elsevier Science, 2004-06)
A series of acetoxy derivatives of androstane and pregnane was deacetylated in organic solvents by microbial lipases. The best results were obtained with lipase from Candida antarctica (CAL B), Candida rugosa (CRL) and ...
Complete and regioselective deacetylation of peracetylated uridines using a lipase
(Springer, 2000-01)
Lipase-catalysed alcoholysis and hydrolysis of 2',3',5-tri-O- acetyluridine (1a) and 2',3',5'-tri-O-acetyl-2'-C-methyluridine (1b) were studied. Conditions for full and regioselective deacetylation of 1a and 1b are shown ...
Effect of the Sugarcane Bagasse Deacetylation in the Pentoses Fermentation Process
(2021-01-01)
Biomass alkaline deacetylation prior to acid pretreatment can be a promising alternative to reduce the toxicity of hemicellulosic hydrolysates and improve second-generation bioethanol production. In this paper, the effect ...
CuFe2O4 Nanoparticles: A Magnetically Recoverable Catalyst for Selective Deacetylation of Carbohydrate Derivatives
(Springer/Plenum Publishers, 2010-09)
An efficient protocol for the rapid room temperature deacetylation of carbohydrate derivatives using CuFe2O4 nanoparticles as an inexpensive and reusable catalyst is presented. After separation of the catalyst with an ...
Deacetylation of furanosides using banana as biocatalyst
(Elsevier Science, 2007-03)
The deacylation under hydrolytic conditions of methyl 2,3,5-tri-O-acetyl-α-d-ribofuranoside, methyl 2,3,5-tri-O-acetyl-β-d-ribofuranoside, methyl 2,3,5-tri-O-acetyl-α,β-d-arabinofuranosides and alkyl 2,3,5-tri-O-acetyl-α ...

Wood capillarity and deacetylation during eucalyptus alkaline impregnation. Suphidity effects and comparison between transverse directions
(de Gruyter, 2013-01)
The relative ion transport capacity of wood, i.e., the Effective Capillary Cross Sectional Area (ECCSA), is determined in this work based on the analogy with the relation between the electrical conductivities of wood and ...
