✦ Synopsis

Abstract

Six new nor‐β‐lapachones have been synthesized from reaction of 3‐bromo‐nor‐β‐lapachone with arylamines. These derivatives have potent anticancer properties against several cell lines. Here, we report complete unambiguous assignments of ^1^H and ^13^C chemical shifts of the new compounds. The assignments were made using a combination of one‐ and two‐dimensional NMR techniques (^1^H, ^13^C, ^1^H^1^H COSY, ^1^H^13^C HSQC, and ^1^H^13^C HMBC). Copyright © 2008 John Wiley & Sons, Ltd.
