This work reports an optimized method for the synthesis of spiro-1,2-dihydropyridines via the cycloisomerization of 3-aza-1,5-enynes, catalyzed by heterogeneous gold(I)–polyoxometalate (POM) hybrids. By replacing traditional homogeneous catalysts with these hybrid systems, we achieved high yields (up to 84% isolated) and shortened reaction times, while minimizing product degradation. The reaction scope was demonstrated across a broad range of substrates, including aryl, alkyl, and heterocyclic derivatives, as well as variations in ring size and nitrogen substituents. These data are the primary NMR FID files of all new compounds of this study.
