Abstract

As a continuation of our research of reactions with alicyclic 1,5,9‐trione 1 and its polycyclic form 2, we have studied their reactions with binucleophiles, e.g., phenylene‐1,2‐diamine and 2‐aminophenol, leading to novel N,O‐containing polycyclic compounds. Trione 1 formed double cyclization products 11 and 12 with 2‐aminophenol and triple cyclization product 15 with phenylene‐1,2‐diamine. Hemiacetal 2 and its dehydration product 5 reacted with binucleophiles through initial isomerization into the intermediate cyclic form 4 of trione 1. Thus, ketone 5 reacted with 2‐aminophenol stereoselectively unlike the hemiacetal 2. The structure and configuration of the reaction products were studied by using advanced spectroscopic techniques including 1D‐ and 2D‐NMR experiments.
