The current laboratory-based practice of organic synthesis renders automation difficult, suffers from safety and environmental hazards, and hampers the implementation of artificial intelligence guided drug discovery. Using a combination of innovative reagent design, hardware engineering, and a simple operating system we provide an instrument capable of executing complex organic reactions with prepacked capsules in a fully automated fashion. The machine conducts coupling reactions and delivers the purified products with minimal user involvement. Two of the most desirable reaction classes – the synthesis of saturated N-heterocycles and reductive amination – were implemented, along with multi-step sequences that provide drug-like organic molecules in a fully automated manner. We envision that this system will serve as a console for developers to provide synthetic methods as integrated, user-friendly packages for conducting organic synthesis in a safe and convenient fashion.
