N2  - Spectroscopic studies have established that panduratin B1 and panduratin B2, isolated from the red rhizomes of a variety of Boesenbergia pandurata  ( Roxb .) Schltr ., are the diastereomers (2RS,1&#8243; RS,2&#8243;SR,6&#8243;RS)- and (2RS,1&#8243;SR,2&#8243;RS,6&#8243;SR)-[7-hydroxy-5-methoxy-2-methyl-2-(4&#8242;-methylpent-3&#8242;-enyl)-2 H-chromen-8-yl][3&#8243;-methyl-2&#8243;-(3&#8243;&#8242;-methylbut-2&#8243;&#8242;-enyl)-6&#8243;-phenylcyclohex-3&#8243;-enyl]methanone. A synthesis of panduratin B mixture has been achieved by chromenylation of panduratin A.
