Abstract

PurposeSynthesis and evaluation of new naphthopyran and related compounds as ultraviolet absorbers.Design/methodology/approachThe new naphthopyran and related compounds were prepared using new synthesis methodology which gave new derivatives via positions not accessible by traditional methods.FindingsA new method for the preparations of naphthopyran was developed. The naphthopyran compounds prepared had promising UV absorption/protection capabilities.Practical implicationsThe new compounds synthesised had unique character enabling them to be used in applications such as UV absorber and sunscreen.Originality/valueNew method of synthesis and the possibility of using the naphthopyran derivatives as UV absorber in many applications.
