A facile synthesis of α-substituted γ-hydroxybutenolides from 3-furfural was achieved using a Baylis−Hillman reaction followed by singletoxygen oxidation. The regioselectivity of this conversion was controlled by using TBAF.

Various dihydrobenzo[c]azepines were synthesized in good yields via Pictet–Spengler cyclization protocol from tosylamide derivatives of Morita–Baylis–Hillman adducts and 1,3,5‐trioxane. The synthesis was carried out in the presence of easily removable montmorillonite K‐10 in short time in high yields.
