The recurvatianes: A suite of oxygenated guaiane sesquiterpenes from Perezia recurvata
Six guaiane sesquiterpenes recurvatiane A-F, including the previously known recurvatiane E and xanthomicrol, were isolated from the Andean Perezia recurvata and their structures determined by spectroscopic evidence. The absolute stereochemistry of recurvatiane A was established by derivatization with (R)- and (S)-α-methoxy-α-phenylacetic acids (MPA). The suite of guaiane-based metabolites here reported, which we have named recurvatianes A-F, provide an example of a pathway by which molecular diversity is generated by the occurrence of specific oxidation reactions in the late biosynthetic steps of the frame structure.
