摘要：In the presence of a strong Lewis base, such as Et3N, trithio-1,8-naphthalic anhydride (3) is easily oxidized. Two improved syntheses of trithio-1, 8-naphthalic anhydride (3) are described. Trithio-1, 8-naphthalic anhydride (3) undergoes Diels-Alder reactions with electron-deficient alkenes to give novel fused heterocyclic compounds (6-11) that then can undergo a novel, gradual desulfuration dimerization with triethyl phosphite to afford 12 and its analogs 13 and 14. The structures of 6-14 are confirmed by microanalysis, IR, and NMR spectroscopy, and MS. (C) 1999 John Wiley & Sons, Inc.
