The antimalarial robustadials A and B have been synthesized in two steps starting from commercially available phloroglucinol comprising a key biomimetic three-component reaction that involves in situ generation of an o-quinone methide via Knoevenagel condensation and subsequent Diels-Alder cycloaddition with (-)-beta-pinene. @ 2006 Elsevier Ltd.

A phloroglucinol derivative, jensenone (1) isolated from leaves of Eucalyptus jensenii has been synthesized for the first time through a short and efficient two-step procedure starting from commercially available phloroglucinol. The methodology provides a simplified route to introduce diformyl moiety for synthesis of biologically active formylated phloroglucinol compounds such as antimalarial robustadials
