With current concerns over the use of fossil resources for chemical synthesis of functional molecules and the effect of current UV absorbers in sunscreens have on the ecosystem, we describe a xylochemical synthesis of different classes of aromatic UV absorbers utilizing cashew nut shell liquid as a non-edible bio-renewable carbon source. Hydroxybenzophenones, xanthones, triazines, and flavones were synthesized starting from cardanol or anacardic acid. Several compounds exhibited favorable UVA and UVB absorption characteristics.
