First stereocontrolled acetylation of a hydroxypropargylpiperidone by lipase CALB

Hydroxypropargylpiperidones rac-1-3 were efficiently obtained by a one-pot three-component coupling reaction; enantioenriched propargylpiperidones were then obtained by a kinetic resolution process using the lipase from Candida antarctica. Lipase CALB has been shown to efficiently catalyse the stereocontrolled acetylation of hydroxypropargylpiperidones rac-3 by promoting stereodiscrimination at the carbinolic centre. The enzymatic catalytic processes allow the separation of the (S,R)- and (S,S)-3 diastereoisomers into the corresponding acetates produced as a (R,S)- and (R,R)-6 diastereoisomeric pair. The CALB was able to discriminate the stereogenic centre of the secondary (R)-enantiomer of rac-3 according to the Kaslauzkas rule. The remote stereogenic centre was not discriminated by the lipase. The functionalised enantioenriched diastereoisomers obtained are important building blocks in organic synthesis. (C) 2010 Elsevier Ltd. All rights reserved.

A fotografia compromissada na espanha: a experiência de Josep Renau nas revistas Orto e Octubre

The aim of this paper is to investigate the environment in which a proposal for photographs and photo montages created in Spain in the 1930s was developed. To achieve this, the experiences of the Spanish artist Josep Renau and his work in the illustrated magazines Orto and Octubre is examined. There is an attempt to explore how the European experience of proletarian culture and photography was circulated and appropriated by the Spanish cultural universe. I believe that during these years Spain became a production hub and disseminator of political iconography which later spread to Mexico and Latin America.

La fortuna de Ramón de la Cruz en el teatre català vuitcentista: els inicis de Josep Robrenyo

Estudia la influència dels sainetes de Ramón de la Cruz en l'escena de Barcelona, i l'esperó que aquest model va suposar per a superar el vell esquema de l'entremés i donar pas al sainet costumista català. S'exemplifica aquest canvi amb "El sarao de la Patacada", de Josep Robrenyo, que pren com a model un títol del saineter madrileny.

Unas «cartas de Francia» de Josep Pla en Destino : Aproximación a la IV República francesa en los inicios de la Guerra de Argelia

This article means a first approach to the information given to its readers by the magazine Destino about the France of the IV French Republic, exactly during Pierre Mendès-France´s term in 1954, and having its origin in four articles published by the journalist and writer Josep Pla just when the Algeria conflict started. That information was determined by the obsessive anti-communist editorial policy of the aforementioned charismatic publication of the francoist Spain.
