Abstract
Purpose - Synthesis and evaluation of new naphthopyran and related compounds as ultraviolet absorbers.Design methodology approach - The new naphthopyran and related compounds were prepared using new synthesis methodology which gave new derivatives via positions not accessible by traditional methods.Findings - A new method for the preparations of naphthopyran was developed. The naphthopyran compounds prepared had promising UV absorption protection capabilities.Practical implications - The new compounds synthesised had unique character enabling them to be used in applications such as UV absorber and sunscreen.Originality value - New method of synthesis and the possibility of using the naphthopyran derivatives as UV absorber in many applications.
