Abstract

Synthesis of nafthopyran is important because of its extensive biological and therapeutic properties such as anti-bacterial, anti-viral and anti-inflammatory. Taking in to account the importance and the principles of green chemistry the use of solfonating starch nano particle as a new catalyst, non-toxic and effective for compression benzaldehyde derivatives, 2-hydroxynaphtalene-1,4-dione and indene-1,3-dione has been used. One-pot quantitative procedure for the preparation of functionalized 12- arylbenzo[g]indeno[1,2-b]chromene-6,11,13(12H)-trione Derivatives in the presence of solfonating starch nano particle under reflux conditions: The advantages of this approach are: The use of available, cheap and non-toxic catalyst, high efficiency, the short of time reaction with less pollution.
