First syntheses of the biologically active fungal metabolites pestalotiopsones A, B, C and F

Beekman, Andrew; Castillo Martinez, Edwin; Barrow, Russell


A synthetic approach accessing the pestalotiopsones, fungal chromones possessing a rare skeletal subtype, is reported for the first time. The synthesis of pestalotiopsone A (1) has been achieved in 7 linear steps (28%), from commercially available 3,5-dimethoxybenzoic acid and subsequently the first syntheses of pestalotiopsone B (2), C (3) and F (4) were performed utilising this chemistry. The key steps include a newly described homologation of a substituted benzoic acid to afford...[Show more]
