Enantioselective organocatalysis has contributed significantly to asymmetric synthesis by delivering highly functionalized complex structural entities with multiple stereogenic centers in high optical purity. Most of enyne system in previous literature was studied to establish by using synergistic/sequential metal catalysis, but it was the few on organic asymmetric cascade reaction. The organocascade reaction was established between 1,3-nitro enynes and 4-hydroxy coumarin to afford pyrano-annulated scaffolds in high yields (up to 88% yield) and excellent stereoselectivities (up to >20:1 Z:E and >99% ee) under bifunctional quinine derived squaramide and DABCO catalysis. The reaction proceeded through sequential conjugate addition, allene formation, intramolecular oxa-Michael 6-endo-dig cyclization and DABCO catalyzed olefin isomerization.
