2-Aminobenzaldehydes as versatile substrates for rhodium-catalyzed alkyne hydroacylation: application to dihydroquinolone synthesis.
Amine for it! A cationic rhodium catalyst, which was assembled insitu from commercial components, promoted the reaction of a range of simple 2-aminobenzaldehydes with terminal and internal alkynes in a series of intermolecular hydroacylation reactions. The products of this reaction, amino-substituted enones, were efficiently converted into the corresponding dihydro-4-quinolones. © 2013 The Authors. Published by Wiley-VCH Verlag GmbH and Co. KGaA.
