• Rhodium-Catalyzed anti-Markovnikov Addition of Secondary Amines to Arylacetylenes at Room Temperature

  DOI：10.1021/ol201453h

  日期：2011.8.5

  An efficient method for synthesis of E-enamines by the anti-Markovnikov addition of secondary amines to terminal alkynes is described. The reaction of a variety of aryl- and heteroarylacetylenes proceeded at room temperature using a combination of a 8-quinolinolato rhodium complex and P(p-MeOC6H4)(3) as a catalyst. The products were obtained as enamines by simple bulb-to-bulb distillation.

  AbstractThe hydroamination of terminal alkynes (RCCH=phenylacetylene, 4‐methylphenylacetylene, 4‐fluorophenylacetylene, 1‐hexyne, methyl 2‐propynyl ether, prop‐2‐yn‐1‐ol) with secondary amines (piperidine, pyrrolidine, morpholine, piperazine, methylpiperazine, 4‐methylpiperidine and 3‐methylpiperidine) was achieved in high yield (up to 99%), regioselectivity (only anti‐Markovnikov product) and stereoselectivity (only E‐isomers) within a maximum of 5 h in reactions catalyzed by the tungsten tetracarbonyl complex cis‐[W(CO)4(piperidine)2] at 90 °C without any additional solvent.magnified image
