摘要

Abstract. The synthesis of [3.3] dithiapyranophanone 6 and 11 is accomplished by use of the two-componentsdilution-principle. Pyrolysis of their bis (su1fones) 7 and 12 gives the [2.2] pyranophanones 8, 9 and 13. Under preservation of conformation the intraannular carbonylfunction is used for the synthesis of methylpyranophanoles 14, 16 and 17. The synthesis of pyrylophanium compounds 15 and 18 is possible by elimination in ...
