With current concerns over the use of fossil resourcesfor chemical synthesis of functional molecules and the effect ofcurrent UV absorbers in sunscreens have on the ecosystem, wedescribe a xylochemical synthesis of different classes of aro-matic UV absorbers utilizing cashew nut shell liquid as a non-edible bio-renewable carbon source. Hydroxybenzophenones,xanthones, triazines, and flavones were synthesized startingfrom cardanol or anacardic acid. Several compounds exhibitedfavorable UVA and UVB absorption characteristics.
