Synthesis and reaction of chiral 4,5-disubstituted 2-oxazolidinones from 3-ethoxy-6-(N-alkyl-N-tert-butoxy- carbonyl)aminohexa-2,4-dienoates in the presence of concentrated sulfuric acid supported on silica gel

Reaction of chiral 3-ethoxy-6-(N-alkyl-N-tert-butoxycarbonyl)amino-hexa- 2,4-dienoates (3) and related compounds with 97% concentrated sulfuric acid supported on silica gel proceeded stereo- and regio-selectively to yield chiral 4,5-disubstituted N-alkyl-2-oxazolidinones (7). Under the limited conditions, 7 were converted into N-alkyl-2-pyrrolylacetates (8) and 2- oxazolidinone derivatives (12) which may serve as a chiral auxiliary.
