Gold-catalyzed heterocyclic syntheses through alpha-imino gold carbene complexes as intermediates
Gold carbene complexes have been recognized as common intermediates in gold-catalyzed organic syntheses. In this field, alpha-imino gold carbene complexes, in the last few years, have emerged as valuable intermediates toward the synthesis of N-heterocycles. This review is dedicated toward formulating a comprehensive compilation of the different methodologies for heterocyclic synthesis, postulating the participation of alpha-imino gold carbene complexes as intermediates. In addition to the scarce examples involving the direct formation of alpha-imino diazo compounds from gold decomposition, the use of nitrogenated nucleophiles, through an initial attack on gold-activated alkynes followed by gold retrodonation and expulsion of a leaving group, constitutes the most commonly employed strategy for achieving this target. This review has been divided into different sections as follows according to the type of N-nucleophile used: azides, aza-ylides, 2H-azirines, isoxazoles and their derivatives, indazoles, and triazapentalenes. A large number of heterocycles, ranging from five- to seven-membered rings, have been efficiently synthesized following this methodology.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 288-14-2, help many people in the next few years.Formula: C3H3NO
