The unexpected formation of a 4-hydroxytetrahydroquinolin-2(1 H)-one from a bicyclo[3.3.1]nonanetrione system and an amino alcohol in the presence of TsOH is reported. The mechanism of this transformation was studied by DFT calculations. The reaction provides an entry to the synthesis of highly functionalized 4-hydroxytetrahydroquinolin-2(1 H)-ones.

The aim of this study was to synthesize the trienynol 3 and to study its cyclization.The substrate was synthesized by a convergent route, the key step being the stereoselective Wittig-Schlosser condensation of the known aldehyde 19 with the phosphorane 18
