La trasmissione delle lingue nello spazio domestico. Uno studio in famiglie italo-brasiliane residenti a San Paolo del Brasile
2021
This paper aims to provide a snapshot of different ways of experiencing the linguistic repertoire (Brazilian Portuguese - Italian) within the intrafamily domain, by mixed families residing in São Paulo, Brazil. In light of the theoretical perspective defined as “linguistics of migration”, together with an investigation methodology that is based on the comparison between declarations and linguistic self-perceptions, obtained through autobiographies and productions, it was possible to assess different types of language transmission practices in a migratory context and to determine the degree of awareness that the first generation develops in order to maintain its linguistic repertoire.
Pig liver esterase (PLE)-mediated resolution of N-substituted 4-benzoyloxy-3-carbomethoxypiperidines: A convenient preparation of 4-hydroxy- and 4-be…

Abstract Pig liver esterase (PLE) afforded smooth chemical resolution of racemic N -substituted 4-(benzoyloxy)-3-carbomethoxypiperidines. The enzyme showed good chemo- and enantioselective properties, thus allowing discrimination between the carbomethoxy and benzoate ester groups, the latter being more easily hydrolyzed. The proposed methodology also represents a practical means for the procurement of N -substituted 4-hydroxy-3-carbomethoxypiperidines in enantiomerically pure form.
Facile synthesis of 2-nitroalkanols by tetramethylguanidine (TMG)-catalyzed addition of primary nitroalkanes to aldehydes and alicyclic ketones
1997
Abstract Tetramethylguanidine-catalyzed addition of primary nitroalkanes to aldehydes and alicyclic ketones constitutes a practical means to perform the nitro-aldol reaction (Henry reaction). The very mild conditions employed, together with the short reaction times, make the procedure tolerant of a range of functionalities and highly versatile for the synthesis of a variety of 2-nitroalkanols.
