Abstract :
An efficient synthesis of novel pentacyclic thiopyrano indole-annulated benzo-δ-sultone derivatives is achieved via intramolecular domino Knoevenagel-hetero-Diels–Alder reaction of 2-formylphenyl (E)-2-phenylethenyl sulfonates and indoline-2-thiones in aqueous medium. The products are formed in good yields with high regio- and stereoselectivity.
