✦ Synopsis

Synthesis,

Reaction, and Structure of Chiral N-Methyl-2-oxazolidinones from 3-Ethoxy-6-(N-methyl-N-tertbutoxycarbonyl)amino-2,4-hexadienoates.

-Treatment of 3ethoxy-6-(N-methyl-N-tert-butoxycarbonyl)amino-2,4-hexadienoates such as (I) with concentrated sulfuric acid supported on silica gel results in stereoand regioselective formation of N-methyl-2-oxazolidinones (II). At lower acid concentrations compounds (III) and (IV) are additionally obtained. Both can be considered as intermediates of the formation of (II). -(KAWANO, T.;
