Note: To use this app an ETH Zurich account is required! The polybox service is used for online data storage and is a safe place for ETH members to exchange data with each other. The polybox service covers the following use case: «polybox – Use it as a logical memory stick – save your data on the ETH campus» As an internal service provider, the ITS System Services (SD) offers all ETH members the service «polybox.ethz.ch» with 50 GB of storage space on the ETH Zurich’s storage facilities. The data stored on the polybox servers are stored on the central storage facilities of the ETH Zurich. Using the service polybox avoids the usage of external (uncontrollable) storage. Sync Clients are provided for an efficient and easy use of the service polybox for all common operating systems (mobile as well as desktop). All ETH members have access to the polybox service. On the first login on «polybox.ethz.ch» with the ETH account, an account with 50 GB of storage is created automatically.

SynStrategy is an organic chemistry app for anyone studying or working in organic synthesis. Its key feature is the categorization of named reactions and unnamed chemical reactions by the functional groups they form, helping students and practitioners navigate the vast landscape of organic transformations. The app features 27 main functional group categories, each further subdivided (for example, Alcohols include primary, secondary, tertiary, allylic, and homoallylic alcohols, and more). This structured organization gives chemists a clearer view of available transformations during synthetic and retrosynthetic analysis. SynStrategy currently includes over 500 organic chemistry reactions, with their synthetic use cases highlighted in more than 400 total synthesis examples. NEW: We've added the mechanisms for a collection of classic named oxidation reactions, with more to come. Each mechanism includes literature references you can look up for further detail. The first set covers the Albright-Goldman, Anelli, Babler-Dauben, Baeyer-Villiger, Ball-Goodwin-Morton, Collins, Corey-Gilman-Ganem, Corey-Kim, Corey-Schmidt, Corey-Suggs, Criegee, Dakin, Davis, Davis Asymmetric, and TEMPO oxidations. Beyond the reference library, SynStrategy includes interactive tools to help you study organic chemistry and organize these transformations. Save specific reactions into custom datasets that can be exported and shared with colleagues. Test your knowledge with the app's study modes: a Quiz system featuring three formats with multiple-choice and advanced questions on chemical reactions and total synthesis steps, plus a traditional Flashcard mode. Both modes include session analytics so you can track your progress. NEW: A Statistics dashboard now lets you review your quiz and flashcard results, see what you've studied, and get an overview of your activity in the app over time (More → Statistics). Whether you're preparing for an organic chemistry (orgo) exam, reviewing named reactions and mechanisms, or planning a synthesis in the lab, SynStrategy aims to be a useful organic chemistry companion. There are countless exceptional total syntheses and synthetically relevant methodologies in the literature, and we aim to grow the selection over time.
