, (2020/09/27)
This disclosure relates to use of cashew nut shell liquid (CNSL) phenolics in the manufacture of molecules having ESIPT character, wherein said molecules are UVA and/or UVB absorbers, and further wherein said molecules are formulated as protectants against UVA and/or UVB radiation. The disclosure extends to use of CNSL in the manufacture of compositions including molecules having ESIPT character for treating and/or preventing sunburn and/or preventing U.V. damage.

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.

o-Iodocardanol, readily available from cardanol by iodination, has been used to prepare a variety of lipophilic benzo[b]furans. 2-Substituted benzo[b]furans have been prepared by a Sonogashira cross-coupling/cyclization process. 2,3-Disubstituted benzo[b]furans have been obtained from o-alkynylcardanols by an oxypalladation/reductive elimination process.
