UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishNew chiral calix[4]arene derivatives have been synthesized by appending at the lower rim amino acid (L-tyrosine, L-aspartic, acid, L-valine, and L-tryptophan) or pinene-like (myrtenyl and homomyrtenyl) units or by distal intrabridging with a binaphthyl amine scaffold. The application of these derivatives in enantioselective catalysis was studied by testing the catalytic activities of the corresponding Ti(IV)/calixarene complexes, prepared in situ, in the asymmetric aldol reaction of Chans silyloxydiene with p-nitrobenzaldehyde.
