Resumen:
A new approach to the synthesis of cyclopenta[b]benzofuran derivatives via reaction of 1,3-dicarbonyl compounds with a,b,g ,d-unsaturated aldehydes is described. The constitution and configuration of the new products have been firmly established by means of residual dipolar couplings (RDCs) and ab initio new products have been firmly established by means of residual dipolar couplings (RDCs) and ab initio compounds with a,b,g ,d-unsaturated aldehydes is described.
