r-5-(α-Halogenobenzyl)-3, t-4-diaryl-c-4-hydroxy-oxazolidin-2-ones as Ring Tautomers of α-(N-Arylaminocarbonyloxy)-β-halogeno-dihydrochalconesThe reaction of chalcone halogenohydrins (1-3) with arylisocyanates does not stop at the stage of the α-arylaminocarbonyloxy-β-halogeno-dihydrochalcones (7), but the cyclic urethanes 4-6 are formed. Compound 7h was synthesized independently. The structure and stereochemistry of 4-6 and 7h were determined by 13C n.m.r. spectroscopy.
