An unusual and highly efficient access to thieno[2,3-b]-benzothiopyran structures
摘要:
Dihydrothieno[2,3-b]-benzothiopyran-4-ones are easily obtained by an intermolecular radical addition to an unactivated olefin using an S-o-fluorophenacyl xanthate followed by a novel, base induced domino cyclisation. (C) 1999 Elsevier Science Ltd. All rights reserved.
