摘要：
Here we describe the divergent, biosynthetically inspired syntheses of (+/-)-rhodonoids C-G and (+/-)-ranhuadujuanine B. The key steps of the Syntheses inelude the construction: of the chromene unit through a formal oxa-[3 + 3] annulation and a biomimetic acid-catalyzed ring Cyclization. Cationic [2 + 2]:cydoadclition is accomplished to form the cyclobutane core of (+/-)-rhcidonoids E and F.
