Efficient syntheses of polycyclic and spirocyclic heterocycles were achieved with high selectivity, broad substrate scope, and scalability. Mechanistic studies provided insights into catalyst-controlled reactivity, expanding synthetic strategies for medicinal and materials chemistry. %L 540 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00005793 %U https://purl.uni-rostock.de/rosdok/id00005793 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00005793-3 %U https://d-nb.info/142068647X/34 %U https://doi.org/10.18453/rosdok_id00005793
