It was shown that the intensity of the peak of the molecular ion in the mass spectra of dibenzo-18-crown-6 derivatives depends to a marked extent on the electronic properties of the substituents on the benzene ring. Fragmentation of the substituents

The reaction of tetracyanoethane with carbonyl compounds proceeds via the scheme of aldol addition with subsequent cyclization of the resulting adducts to give 5-amino-2,3-dihydrofuran derivatives, the structures of which were confirmed by the 13C NM

The stereochemistry of the successive addition of two different dienophiles, viz., N-phenylmaleinimide and 4-phenyl-1,2,4-triazoline-3,5-dione, to 2-pyrones was studied. The configurations of the mixed adducts (bisimides) obtained were established by
