A contribution to the elucidation of oil migration mechanisms through water-wet sediments: Crushed rock environment as example
(Journal of the Serbian Chemical Society, 1996)
In order to gain insight into oil transformations which occur during migration, and to contribute to the elucidation of migration mechanisms in water-wet environments, the content and composition of heavy fuel oil from an ...
GC-MS in crude oil correlation studies - Effects of biodegradation on sterane and terpane maturation parameters
(Journal of the Serbian Chemical Society, 1996)
GC-MS was applied in order to determine the effects of biodegradation on steranes and terpanes in crude oils. Sterane and tcrpane maturation parameters were correlated in 36 crude oils, biodegraded to various degrees (28 ...
A novel m-CPBA oxidation: p-quinols and epoxyquinols from phenols
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
Steroidal quinols were obtained on large scale in 50-57% yield, together with syn-epoxyquinols. The reaction conditions can be adjusted to afford only the corresponding steroidal epoxyquinol in 51-54% yield. Copyright (C) ...
Diterpenes from Achillea clypeolata
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The isolation of 16 alpha,17-epoxy-ent-kaurane (a known compound), 3 alpha-acetoxy-16 alpha,17-epoxy-ent-kaurane and 19-acetoxy-16 alpha,17-epoxy-ent-kaurane from roots of Achillea clypeolata is reported. Copyright (C) ...
The synthesis of lactam analogues of fentanyl
(Royal Soc Chemistry, Cambridge, 1996)
Fentanyl, sufentanil and alfentanil are clinically widely used anaesthetics and are structurally related to drugs with entirely different pharmacological activity such as droperidol, loperamide and lorcainide, etc. Therefore, ...
Conformational study of fentanyl and its analogs .1. Conformational space of the N-phenethyl substituent
(John Wiley & Sons Ltd, W Sussex, 1996)
The computational method, based on molecular mechanics, with Monte Carlo type searching in dihedral angle space, was applied to the study of seven physiologically highly active fentanyl analogs, with different substituents ...
Preparation of secondary amines by reductive amination with metallic magnesium
(Royal Soc Chemistry, Cambridge, 1996)
A novel and efficient method for the preparation of secondary amines by reductive amination of carbonyl compounds with primary amines has been developed, The reduction, effected with metallic magnesium in methanol, utilizing ...
Labelling of breast carcinoma, thyroid carcinoma and melanoma with manno- and galacto-specific lectins from marine invertebrates
(Luigi Ponzio E Figlio, Pavia, 1996)
Three marine invertebrate FITC-labelled lectins, CNL, GCL, and GSL, isolated respectively, from the sponges Chondrilla nucula, Geodia cydonium, and the hexacoral Gerardia savaglia, were used as potential diagnostic tools ...
Transition-metal complexes with hydrazides and hydrazones .7. Dioxomolybdenum(VI) complexes of salicylaldehyde p-hydroxybenzoylhydrazone and their thermal stability
(John Wiley & Sons Ltd, W Sussex, 1996)
Several new complexes of dioxomolybdenum(VI) of the general formula [MoO2(L)S], where L is the dianion of salicylaldehyde p-hydroxybenzoylhydrazone and S denotes H2O, MeOH, py, PPh(3), DMSO or DMF, were synthesized and ...
