Abstract
The reaction of chalcone halogenohydrins (1-3) with arylisocyanates do es not stop at the stage of the rylaminocarbonyloxy-beta-halogeno-dihy drochalcones (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 C-13 n.m.r. spectroscopy.
