摘要

Abstract Five 1, 1, 3-trisubstituted naphtho [2, 3-c] pyran-5, 10-dione derivatives were designed and synthesized in five steps from 2-acetyl-1, 3-indandione. Prepared quinones 6a–e instantly changed from either red or blue to yellow or orange red, when treated with sodium borohydride in methanol. The resulting reduced hydroquinones 9a–e reverted to their original colors within a few minutes after the reducing agent was consumed or ...
