WebOn the basis of these observations the sample was selected for further investigation. The CH3OH extract of the sponge was fractionated by RP-HPLC to yield two meroterpenoids, the new metabolite puupehenol (1) and the known compound puupehenone (2).20 The molecular formula of 1 was determined to be C21H30O4 by accurate mass measurement. WebSubjection of the key tetracyclic chromanone 19 to different reduction conditions also led to the formal syntheses of (−)-puupehenol 7 and (+)-puupehedione 8. All of these indicate the great potential of the developed strategy in the synthesis of a diverse array of chromane-containing meroterpenoids which will provide a solid foundation for their further SAR …
