Abstract
The tetrafunctional products 3 and 6 were synthesized via Diels‐Alder reaction of bis(2‐pyrone) with bismaleimides in mol ratio 1:7. The chemical structure of these products was determined by 1H‐NMR spectroscopy; the high degree of purity was confirmed by means of elemental analysis. The cyclization of the tetraimide 3 with 2 mol monopyrone 7 to the bicycle 8 was carried out. © 1995 John Wiley & Sons, Inc.Keywords
