Azomethine Ylide Cycloaddition of 1,3- dienyl esters: Highly regio- and diastereoselective synthesis of functionalized pyrrolidinochromenes
Keyword(s):
An efficient protocol for the synthesis of tricyclic pyrolidinochromenes has been developed via an intramolecular 1,3-dipolar cycloaddition of azomethine ylides generated in situ from 1,3- dienyl ester tethered O-hydroxyarylaldehyde and...
