Favoring Trienamine Activation through Unconjugated Dienals: Organocatalytic Enantioselective Remote Functionalization of Alkenes
(Wiley-VCH, 2014-01-29)
Unconjugated 2,5-dienals are more reactive substrates
than the corresponding fully conjugated a,b,g,dunsaturated
aldehydes towards organocatalytic activation
through trienamine intermediates. This difference in ...
Novel topoisomerase I inhibitors. Syntheses and biological evaluation of phosphorus substituted quinoline derivates with antiproliferative activity
(Elsevier, 2018-02-22)
This work describes the synthesis of 1,2,3,4-tetrahydroquinolinylphosphine oxides, phosphanes and phosphine sulfides as well as that of quinolinylphosphine oxides and phosphine sulfides, which were synthesized in good to ...
Catalytic Enantioselective Synthesis of Tertiary Thiols From 5H-Thiazol-4-ones and Nitroolefins: Bifunctional Ureidopeptide-Based Brønsted Base Catalysis
(WILEY-VCH Verlag, 2013-09-17)
The direct catalytic reaction between an enolizable carbonyl compound and an electrophile under proton-transfer conditions has emerged as a challenging versatile transformation in organic synthesis.1 Over the last years ...

(Elsevier, 2016-11-16)
Este trabajo analiza tanto el efecto de los nanocristales de celulosa en las propiedades finales de espumas flexibles de poliuretano basadas en castor oil y maíz, sino que además se realiza un análisis en profundidad sobre ...
Association among obesity-related anthropometric phenotypes: analyzing genetic and environmental contribution
(Wayne State University Press, 2012-04-01)
Obesity has become a public-health and policy problem in many parts of the world. Epidemiological and population studies in this field are usually based on different anthropometric measures; however, common genetic and ...
Negotiation of Meaning Strategies in Child EFL Mainstream and CLIL Settings
(Wiley, 2016)
Research on child English as a second language (ESL) learners has shown the benefits of task-based interaction for the use of different negotiation of meaning (NoM) strategies, which have been claimed to lead to second ...

Use of native species to improve carbon sequestration and contribute towards solving the environmental problems of the timberlands in Biscay, northern Spain.
(Elsevier, 2013-03-15)
The rapid transformation of natural forest areas into fast-growing exotic species plantations, where the main objective is timber and pulp production, has led to a neglect of other services forests provide in many parts ...
Afasia euskaraz aztertzeko tresna berria bidean: CAT testaren egokitzapenaren gakoak eta estandarizaziorako urratsak
(EUE, 2018-12-01)
Afasiaren inguruko ikerketan eta tratamenduan ezinbestekoa da munduko hizkuntza-aniztasuna
kontuan hartzea; izan ere, hizkuntzen ezaugarri gramatikalek afasian agertzen diren sintomak
baldintzatzen dituzte. Bestalde, ...
A statistical investigation into the sharing of common genetic factors between blood pressure and obesity phenotypes in nuclear families from the Greater Bilbao (Spain)
(Lippincott, Williams & Wilkins, 2010)
Objectives: Several obesity phenotypes (e.g. body mass and fat, fat distribution) have been suggested to be a risk for elevated blood pressure. This study was undertaken to determine the heritability of four blood pressure ...
