Full textA partir de l'estudi i anàlisi d'edificis existents ,i utilitzant el modelat tridimensional hom pot entendre i per tant explicar, els principals mecanismes de disseny i construcció d'edificis històrics fent-los comprensibles a públics no especialitzats. El coneixement de les eines que ens ofereixen avui els softwares de CAD permeten aprofundir molt en el desenvolupament de mecanismes descriptius de l'edifici, abans de construir-los o tornant-los al seu estat originari si han sigut enfonsats o parcialment enfonsats. La tesi aprofundeix en aquests recursos a partir de diversos exemples, obres d'Antoni Gaudí, arquitecte referent a Catalunya, incidint especialment en la geometria i en la forma que els defineix. El grau d'expertesa assolit i el constant procés de formació ens doten de capacitat per transmetre (a futures generacions) recursos per tal d'assolir amb criteri i rigor la documentació necessària pera ser bons professionals en el camp del disseny, l'enginyeria i l'arquitectura.

Full textTerreinol is a natural product isolated from Aspergillus terreus. Due to its unique structure and our interest in evaluate its bioactivity, we propose herein a novel synthetic route toward this compound. Our synthetic approach is based on the V (II)-mediated pinacol cross coupling reaction between two electronically distinct aldehydes. This study describes the synthesis of model aromatic substrates (A e 16) to be evaluated with respect to their efficiency in coupling to the aliphatic aldehyes 4-6. Therefore, 4-benzyloxy-butanal (4) and 3,5-dimethoxybenzaldehyde (A) were obtained with 57% (2 steps) and 29% (4 steps) respectively. The formation of homocoupling adducts in the pinacol reaction of these aldehydes suggests a reactivity inconveniently high of the aliphatic component, possibly due to quelation of OBn oxygen atom to the vanadium center. Aiming at the inhibition of quelation, two other aliphatic aldehydes, 5 and 6, were synthesized (two steps from 1,4-butanediol, 27% and 34% global yield, respectively. Besides, a particularly activated tetrasubstituted aromatic aldehyde 16 (obtained in 7 steps, 15%) was used. Nevertheless, the pinacol cross coupling between aldehydes 6 e 16 showed to be slow and furnished a complex mixture of byproducts majorly constituted of decomposition compounds from starting materials. These information indicate the actuation of additional unfavorable electronic and/or steric characteristics that could inhibit the cross coupling. Further studies are crucial to elucidate these propositions.
