AminationO 0268 Synthesis of a Simplified Version of Stable Bulky and Rigid Cyclic

(Alkyl)(amino)carbenes, and Catalytic Activity of the Ensuing Gold(I) Complex in the Three-Component Preparation of 1,2-Dihydroquinoline Derivatives. — A new cyclic aminocarbene gold(I) complex (I) is prepared and used in the multicompo-nent preparation of 1,2-dihydroquinoline derivatives. The feasibility of this reaction al-lows significantly enlarging the scope to the preparation of related nitrogen-containing heterocycles. Additionally, the efficiency of (I) is illustrated by the hydroamination of internal alkynes with secondary dialkylamines, a process with little precedent. — (ZENG, X.; FREY, G.
