1987
O-Methyl-O-(trimethylsilyl) keten acetals2 were regioselectively alkoxyalkylated by 2-alkoxy-1,3-dioxolanes1 in the presence of zinc chloride. This method represents a good way for synthesis of α-protected β-keto carbonic esters4.

Silicon-guided rearrangement of 10-methyl-4,5-epoxydecalins. Methyl versus methylene migration
2003
The Lewis acid-promoted rearrangement of two 10-methyl-4,5-epoxydecalins bearing a trimethylsilyl (TMS) group on C-1 or C-9 has been studied. Migration of the C-9 methylene group to C-5 is the major reaction pathway when the TMS and the oxirane groups are on the same ring while methyl migration results exclusively when they are on different rings.

Syntheses of polyfunctionalized resveratrol derivatives using Wittig and Heck protocols
2012
Improved protocols for Wittig reaction and palladium-catalyzed Heck coupling give expedient access to a series of unprecedented polyfunctionalized artificial-resveratrol derivatives. In the modified Wittig protocol, trimethylsilyl was used as a highly valuable protective group of the phenolic functions of starting aromatic materials. A clean O-alkylation of hydroxylated stilbenes with ethylene carbonate was also conducted. Thus, Wittig reaction followed by hydroxyethylation take place one-pot with only carbon dioxide as waste. Additionally, a palladium-catalyzed Heck coupling strategy was developed by using ferrocenyl phosphane ligands, and multi-functionalized hydroxylated stilbenes were o…
Costruzione della Sicilian Experience. Il caso di Anna Tasca Lanza Cooking School
2020
La Sicilia è storicamente oggetto di narrative di stampo marcatamente edonistico, anche di recente casi rispecchiate e alimentate da casi editoriali di grande successo. Con l’imporsi di nuovi trend turistici improntati alla scoperta di specialità gastronomiche e vinicole locali, il settore turistico dell'isola gode di un ciclo particolarmente positivo. Le strutture di produzione e distribuzione agroalimentare e le realtà ricettive del territorio si stanno evolvendo per assecondare questo nuovo tipo di domanda, con effetti prevedibili di patrimonializzazione e ricostruzione semiotica della cultura alimentare tipica. Tra le realtà più in vista, nel settore, c’è la scuola di cucina Anna Tasca …
Natura e fondamento dell’azione revocatoria ordinaria e fallimentare
2022
Lo scritto esamina la natura giuridica della azione ordinaria e della azione revocatoria e il fondamento di queste azioni, che viene rinvenuto in un illecito commesso dal debitore e dal terzo. Nel caso di atti a titolo gratuito invece la revoca mira a evitare un ingiustificato arricchimento del terzo. The paper examines the juridical nature of the actio pauliana and of the bankrupty invalidation action and the reasons of these actions, which are based on a tort committed by the debtor and by the third party. In the case of free-of-charge deeds, however, these actions aim to avoid unjustified enrichment of the third party.
Colección Fortuny. Patrimonio textil en la subasta Drouot de 1875
2018
La colección de tejidos antiguos de Mariano Fortuny Marsal (1838-1874) salió a la venta en la subasta del Hôtel Drouot de París, pocos meses después de la temprana muerte del pintor. El estudio de varios catálogos manuscritos nos ha servido para conocer los precios y compradores de cada una de las referencias. Estos datos nos han permitido realizar un estudio comparativo entre diferentes categorías. Se ha realizado un análisis de la tipología de las piezas, según su valoración en el mercado, para establecer los aspectos que influyeron en la cotización de las mismas. The collection of antique fabrics of Mariano Fortuny Marsal (1838-1874) went on sale at the auction of the Hôtel Drouot in Par…
Comunicare il restauro
2017
Le nuove, estese concezioni del patrimonio culturale collegate alle tecnologie della comunicazione, devono essere l'occasione per una cultura dell'integrazione che faccia lavorare insieme le due componenti, Heritage e Digital- in una visione consapevolmente interdisciplinare, forse anche transdisciplinare, che lavori alla ri-composizione dei saperi e a quella di essi con il contesto fisico-sociale. This paper puts forward a comparison between the traditional way of communicating cultural heritage and a new approach that not only involves the physical use of cultural assets, but also the understanding of their identity and history, through intangible technological systems of communication.
