A Straightforward Entry into Polyketide Monoprenylated Furanocoumarins and Pyranocoumarins
摘要:
A regioselective synthesis of 5-methyl- and 5-ethyl-4-hydroxycoumarin (Ib and Ic, respectively) is described. Starting from these compounds, several prenylated polyketide coumarins of limited availability from natural sources and important taxonomic relevance were prepared.
