t-Butyl 3,4-dialkyl-1H-pyrrole-2-carboxylates were oxidized with o-chloranil in the presence of MeOH to afford the corresponding 5-methoxypyrrolin-2-one derivatives. The resulting 5-methoxypyrrolin-2-one was reacted with various nucleophiles under acidic conditions to afford the functionalized pyrrolinone derivatives in good yields.
