utilising this chemistry. The key steps include a newly described homologation of a substituted benzoic acid to afford phenylacetate derivatives utilising Birchreductivealkylation conditions, a microwave mediated chromanone formation proceeding through an oxa-Michael cyclisation, and an IBX induced dehydrogenation to the desired chromone skeleton. The synthetic natural products were completely characterised
