Vinylogs of N-acyl N,O-acetals are formed in good yields by anodic oxidation, in methanol or water, of S-enaminoesters derived from pyroglutamic acid. These new acetals react easily with nucleophiles or silylated amines. Anodic oxidation of N-acylamino acids was first reported in 1979.l The N-acyl N
2-thiaisatoic anhydride 1 and 3-thiaisatoic anhydride 2 were synthesized in large scale under microwave heating conditions with 85% and 67% yields respectively. The reactivity of these two compounds was studied towards various nucleophiles and appeared to be generally different from that of isatoic
