“…Numerous aurone syntheses were reported in the literature: the Wheeler aurone synthesis from chalcone dihalides, oxidative cyclization of 2‘-hydroxychalcones, and ring closure of o -hydroxyaryl phenylethynyl ketones . These methods give generally good stereoselectivity, but they usually cannot completely prevent the formation of flavones.…”

Versatile and Expeditious Synthesis of Aurones via Au^I-Catalyzed Cyclization

et al. 2008

Aurones are conveniently formed in a three-step procedure including a goldI-catalyzed cyclization of 2-(1-hydroxyprop-2-ynyl)phenols as a highly regio- and stereoselective key step. A wide diversity of derivatives can be obtained starting from substituted salicylaldehydes. Synthesis of natural 4,6,3',4'-tetramethoxyaurone and structure revision of two natural products (dalmaisione D and 4'-chloroaurone) were achieved.

“…This easy three step sequence was reported for the construction of aurone skeletons [172], natural flavonoids. Aurones possess many biological properties [173][174][175][176][177], and due to this many groups were interested in the development of convenient synthetic pathways [178][179][180][181][182][183][184]. The best results were reported with goldcatalyzed oxycyclization and have advantages such as excellent selectivities, milder reaction conditions, and avoided the formation of byproducts like flavones [185].…”

Applications of metal and non-metal catalysts for the synthesis of oxygen containing five-membered polyheterocylces: a mini review

et al. 2019

View full text Add to dashboard Cite

The investigation of methods for the chemical synthesis is a growing area of interest due to increasing environmental issues. The use of catalysts in organic reactions has gained extensive interest. Metal and non-metal catalysts provided a new improved alternative to traditional methods in modern synthetic chemistry. The aim of present review is to focus on the applications of metals and non-metals for the synthesis of oxygen containing five-membered polyheterocylces.
