The quality control of has been greatly improved by macroscopic and microscopic identification and chemical profiling described in Chinese Pharmacopoeia since 2005. However, these methods have their own limitations, e.g.

Copper(I)-mediated cascade reactions: an efficient approach to the synthesis of functionalized benzofuro[3,2-d]pyrimidines.

A novel cascade reaction was developed for the synthesis of diverse members of a series of benzofuro[3,2-d]pyrimidine derivatives. The process utilizes readily prepared 3-chlorochromenones and various commercially available amidines and their analogues as starting materials. This tandem reaction is promoted by using a simple copper(I) reagent and involves a chemoselective Michael addition-heterocyclization-intramolecular cyclization sequence.
