Butanolides as a common feature of Iryanthera lancifolia and Virola surinamensis
(Elsevier B.V., 1998-11-01)
A comparative phytochemical study between pericarps of Iryanthera lancifolia and Virola surinamensis showed that the first one contains a new pair of epimeric 2-alkenyl-gamma-lactones, besides an aryltetralinic lignan and ...

Psammophilous halacarid mites (Trombidiformes, Halacaridae) from the North Coast of Sao Paulo State, Brazil
(MAGNOLIA PRESS, 2011)
Five halacarid species are reported from the Brazilian coast for the first time. Scaptognathides delicatulus, formerly known only from its type locality in Kuwait; Scaptognathus gibbosus, known from Galapagos and Somalia; ...
Highly stereoselective aldol reactions of lithium ester enolates with (Rs)-2-(p-tolylsulfinyl)cyclohexanones
(1996)
Aldol reactions lithium alkyl acetates (LiCRR″CO2R′) with (RS)-2-(p-tolylsulfinyl)cyclohexanone (1) (as an epimeric mixture at C-2) take place with very efficient control of the configuration at the tertiary hydroxylic ...
Revision of the family Carabodidae (Acari: Oribatida) XIII. Congocepheus camerunensis sp. nov. from Cameroon and Synkrotima zimbabwae gen. nov., sp. nov. from the Republic of Zimbabwe
(Systematic and Applied Acarology Society, 2017-10)
Congocepheus camerunensis sp. nov. from Cameroon and Synkrotima zimbabwae gen. nov., sp. nov. from Zimbabwe are described using optical and Scanning Electron Microscopy (SEM). Congocepheus camerunensis is similar to C. ...
Photo-Fries Rearrangement of Some 3‑Acylestrones in Homogeneous Media: Preparative and Mechanistic Studies
(American Chemical Society, 2019-05)
Irradiation of a series of 3-acylestrones under a nitrogen atmosphere in cyclohexane, acetonitrile (MeCN), and methanol (MeOH) was investigated under steady-state conditions. The molecules underwent the photo-Fries ...

Stereoselective synthesis of azetidine-derived glutamate and aspartate analogues from chiral azetidin-3-ones
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The stereoselective syntheses of cis conformationally constrained glutamate and aspartate analogues, containing an azetidine framework were accomplished from (S)-N-tosyl-2-phenylglycine in moderate overall yields. The key ...
Phylogenetic vision of bile acids Visión filogenética de los ácidos biliares.
(1994)
Bile acids are the most important solutes of bile: they are essential in cholesterol degradation, solubilization and excretion; they are determinants of bile flow and secretion; and their role is crucial in the intestinal ...
On the identity of Pterodectes ralliculae Atyeo and Gaud, 1977 (Astigmata: Proctophyllodidae)
(Taylor & Francis Ltd, 2010-01-01)
The feather mite Pterodectes ralliculae Atyeo and Gaud, 1977 (Proctophyllodidae: Pterodectinae) is the only proctophyllodid known from rallids (Gruiformes, Rallidae). Based on re-examination of the type material, this mite ...
