Syntheses of (+/-)-Bavachromanol and (+/-)-7-O-Methylpsoralenol

Total synthesis of (+/-)-bavachromanol (1) and partial synthesis of (+/-)-7-O-methylpsoralenol (2) are described.The key step in the synthesis of 1 is the conversion of 4-benzyloxy-3-prenylresacetophenone (II) to (+/-)-3-hydroxychroman (III) by treatment with m-chloroperbenzoic acid.Similarly, synthesis of 2 has been achieved in a single-step reaction of m-chloroperbenzoic acid with 7-O-methylneobavaisoflavone.
