Stereoselective synthesis has been emerging as a resourceful tool because it enables the
obtaining of compounds with biological interest and high enantiomeric purity. Flavonoids are …

This review focuses on the synthesis and biological activity of flavones and their related
flavonoidic compounds, namely flavonols and aurones. Among the biological activities of …

Flavones are present in a variety of medicines and natural products and are important
structural motif due to their unique mode of physiological action. Hence the structural …

An efficient TaBr5 (5–10mol%)-catalyzed Biginelli reaction under solvent-free conditions for
one-pot syntheses of 3, 4-dihydropyrimidin-2-(1H)-ones (DHPMs) and their thione analogs …

Flavonoids are a class of natural products, found in a wide range of vascular plants and
dietary components. Their low toxicity and extensive biological activities, including anti …

A diversity‐oriented approach for the synthesis of various structurally different molecular
