A simple and efficient method for the synthesis of highly substituted spiroindoline derivatives is presented. A Fischer indolization is combined with Ugi-type reactions to explore the chemical space concerning this privileged structure. Moreover, spiropiperidine derivatives could be postmodified for the production of a small-molecule library that will be part of the Joint European Compound Library of the European Lead Factory.
