Synthesis of diethyl 2H‐naphtho[2,1,b]pyran‐2,3‐dicarboxylate and some related compounds as UV absorbers
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.
