The Copper‐Catalyzed Decarboxylative Coupling of the sp3‐Hybridized Carbon Atoms of α‐Amino Acids

Abstract: Joined at the Cs: A novel intermolecular decarboxylative C sp 3C sp 3, C sp 3C sp 2, and C sp 3Csp coupling catalyzed by CuBr and using α‐amino acids as starting materials has been developed (see scheme). Various functionalized nitrogen‐containing compounds were obtained by this method.

“…The combined organic layers were dried over MgSO4, filtered and the solvent was evaporated under reduced pressure. The resulting solid was triturated in hexane (10 mL 7,132.5,132.4,119.7,117.6,117.6,44.9,18.3,11.1;IR ν 3288 (w), 3088 (m), 2949 (m), 2894 [6] Y. LI, J. Brand, J. Waser, Angew.…”

“…In 2009, Chao-Jun Li and co-workers reported the decarboxylative alkynylation of amino acids using a copper catalyst and di-tert-butyl peroxide as stoichiometric oxidant at 110 °C (Scheme 2, A). [6] In 2010, Seidel and co-workers [7] and Chao-Jun Li and coworkers [8] used the condensation of aldehydes or ketones instead of the peroxide oxidant (Scheme 2, B). The copper-catalyzed method was extended to -cyano carboxylic acids by Xu and co-workers in 2013 using alkynyl bromides (Scheme 2, C).…”

“…Therefore, using α-amino acids as the nitrogen-containing motifs to construct heterocycles are very attractive synthetic method. Many reactions about the decarboxylative of α-amino acids have been developed in recent years [32][33][34][35][36][37][38][39][40][41][42]. For example, Fu and our group have reported the synthesis of quinazolinones via a decarboxylative coupling of α-amino acids [43,44].…”

“…Während die Knüpfung von C(sp)-C(sp 2 )-Bindungen durch die Sonogashira-Reaktion [6] gut entwickelt ist, gibt es nur wenige Methoden für die Kupplung zwischen C(sp 3 )-und C(sp)-Zentren. [7][8][9][10] Diese Reaktionen werden durch konkurrierende b-Hydrideliminierung und eine langsame reduktive Eliminierung erschwert. [7] Die meisten der heute vorliegenden Methoden beruhen auf der Kupplung einer metallorganischen Alkinylverbindung oder eines Alkins mit einem Alkylhalogenid.…”

“…[10] Stereoselektive Varianten dieser Reaktionen sind selten und wurden bis dato nur für C(sp)-C(sp 3 )-Kreuzkupplungen entwickelt. [8f,g] Vor kurzem konnten wir zeigen, dass sich die Pd-Katalyse zur Durchführung hoch diastereoselektiver C(sp 3 )-C(sp 2 )-Negishi-Kreuzkupplungen zwischen substituierten Cycloalkylreagentien und (Hetero)Arylhalogeniden eignet.…”
