General Introduction

Dicarbonyl derivatives are an important class of compounds in view of their distinct structural properties and high synthetic utility, particularly as building blocks for the elaboration of polycarbocyclic frameworks and heterocyclic nuclei. Thus, 1,3-diketones are useful skeletons for the construction of the benzopyran-4-one ring system present in chromones, flavonoids, and the like, as illustrated by the diketone 180 (Scheme 108), which is used as a key intermediate for the syntheses of fungal metabolites such as fulvic acid (181)[‌521‌,‌522‌] and citromycetin (182).[‌523‌,‌524‌]
