As part of a program towards the syntheses of novel tricyclic compounds, some derivatives of thieno[3,4‐ b ]‐[1,5]benzoxazepin‐10‐one system 1 were prepared and were subsequently subjected to reduction reactions using lithium aluminum hydride. Although thienobenzoxazines 4 were obtained as the sole product of the reduction in most cases, unusual ring‐opened products, namely 3‐hydroxymethylthiophenes 5 , were also formed during several reductions.
