ChemInform Abstract
The carbonyl oxide (IV), which is derived in situ from the reaction of furan (I) with singlet oxygen, reacts in the presence of isocyanate (II) in a 1,3-dipolar cycloaddition to the title heterocycle (III) besides other products. Compounds such as (III) are structurally related to interesting biologically active products.
