Oxidative functionalization of a halimane diterpenoid achieved by fungal transformation
(2019-05-01)
Regio and stereoselective activation of sp 3 C–H bonds remain one of the major advantages of biocatalysis over traditional chemocatalytic methods. Herein, we describe the oxy-functionalization of halimane diterpenoid 1 by ...

Bond strength of reline resins to aged-simulated denture base acrylic resin
(2016-01-01)
Objectives: The aim of this study was to evaluate the bond strength of different direct reliners to acrylic resin for denture base. Materials and methods: Double-cone specimens were made: HA.heat-cured acrylic resin―(n = ...
The illiquidity component of corporate bond spreads
(2017)
We find that illiquidity remains a major factor in explaining corporate spreads. Illiquidity is second only to the credit risk itself. This effect is surprising given that the corporate debt trading activity has more than ...
The position of the double bond in monounsaturated free fatty acids is essential for the inhibition of the nicotinic acetylcholine receptor
(Elsevier B.V., 2012)
Abstract: Free fatty acids (FFAs) are non-competitive antagonists of the nicotinic acetylcholine receptor (AChR). Their site of action is supposedly located at the lipid-AChR interface. To elucidate the mechanism involved ...
Thermodynamic Stabillity of Hydrogen-Bonded Systems in Polar and Nonpolar Environments
(JOHN WILEY & SONS INC, 2010)
The thermodynamic properties of a selected set of benchmark hydrogen-bonded systems (acetic acid dimer and the complexes of acetic acid with acetamide and methanol) was studied with the goal of obtaining detailed information ...
Oxidação aeróbica de alcóois terpênicos naturais catalisada por sais de Paládio (II)
(Universidade Federal de Minas GeraisUFMG, 2016-07-13)
In the present work, several catalytic processes for the aerobic (i.e. using molecular oxygen as the stoichiometric oxidant) oxidation of bio-renewable natural terpenes available from various essential oils and showing a ...
Síntese de produtos fragrantes através da oxidação catalítica de olefinas de origem natural
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAPrograma de Pós-Graduação em QuímicaUFMG, 2008-02-25)
Linalool, a monoterpenic allylic alcohol, has been efficiently and selectively oxidized by dioxygen in methanol and ethanol solutions using a chloride-free Pd(OAc)2/Cu(OAc)2 catalytic system under non-acidic conditions. ...
