Lo scopo di questa tesi di laurea è di presentare e documentare i risultati della tesi svolta in contesto aziendale presso la start-up "Marketcloud". L’obiettivo è stato quello di progettare, sviluppare e documentare una SDK REST in linguaggio Swift 2.1 per interfacciare eventuali future applicazioni iOS con le API Marketcloud. Viene fornita una panoramica sulla start-up in questione, sul linguaggio Swift, sulle motivazioni dietro lo sviluppo dell’SDK e sulle varie fasi di progettazione e sviluppo di quest’ultima. Tutto il lavoro in questione è documentato e reperibile sul repository Github di riferimento all'indirizzo https://github.com/Marketcloud/marketcloud-swift-sdk.

A simple and convenient synthesis of 3-methylene-4-aryl-1,3,4,5-tetrahydro-benzo[b][1,4] diazepin-2-ones was accomplished by the SN2 nucleophilic substitution of the acetates of Baylis-Hillman adducts of acrylate with 1,2-phenylenediamines followed by base-mediated intramolecular cyclization. On the other hand similar substrates derived from the Baylis-Hillman adducts of acrylonitrile via Pinner’s reaction leads to 3-arylmethylene-4,5-dihydro-3H-benzo[b][1,4]diazepin-2-ylamines in good yields..

The synthesis of the three N,N′-di(4-coumaroyl)tetramines, i.e., of (E,E)-N-{3-[(2-aminoethyl)amino]propyl}-3,3′-bis(4-hydroxyphenyl)-N,N′-(ethane-1,2-diyl)bis[prop-2-enamide] (1a), (E,E)-N-{4-[(2-aminoethyl)amino]butyl}-3,3′-bis(4-hydroxyphenyl)-N,N′-(ethane-1,2-diyl)bis[prop-2-enamide] (1b), and (E,E)-N-{6-[(2-aminoethyl)amino]hexyl}-3,3′-bis(4-hydroxyphenyl)-N,N′-(ethane-1,2-diyl)bis[prop-2-enamide] (1c), is described. It proceeds through stepwise construction of the symmetric polyamine backbone including protection and deprotection steps of the amino functions. Their behavior on TLC in comparison with that of 1,4-di(4-coumaroyl)spermine (=(E,E)-N-{4-[(3-aminopropyl)amino]butyl}-3,3′-bis(4-hydroxyphenyl)-N,N′-(propane-1,3-diyl)bis[prop-2-enamide]; 2) is discussed.
