✦ Synopsis

A bs tract: N-methyl-2-oxazolidinones (4) axe obtained stereo-and regio-selectively when 3-ethoxy-6-(N-methyl-N-tert-butoxycarbonyl)amino-2,4-bexadJenoates (1) are treated with concentrated sulfuric acid (1.0 equiv.) supported on silicagel in dichloromcthane at 0 "C. 4 were shown to be intermediates for the construction of N-methylpyrrole ring. The structure and properties of 4 and related compounds a~ also described.
