    Abstract: 石斛為蘭科多年生草本植物,種類繁多,其用藥部位為莖。在早期的中藥中記載,石斛具生津益胃、溼陰潤肺及解熱止渴的功效,是重要的常用上品中藥。
    2,3,4,7-Tetramethoxy-9,10-dihydro-phenanthrene與2,5,6,7-tetramethoxy-9,10-dihydrophenanthren-1-ol是大爪石斛中所分離出的兩種成分,由於具有很好的抗腫瘤活性,因此引起我們合成這些化合物以及其類似物之興趣。我們利用triphenyl(3,4,5-trimethoxy-benzyl)phosphonium bromide與苯環上具有不同取代基之benzaldehyde反應來形成二苯乙烯類化合物,經過氫化反應後,再與PhI(OCOCF3)2及BF3˙Et2O混合液於低溫下進行環化反應,得到一系列以2,3,4-trimethoxy-9,10-dihydrophenanthrene為基本架構的二氫菲類化合物,並以各種光譜確認其結構以供研究此系列化合物的抗腫瘤活性。
