1,2-Amino alcohols and -aminocarbonyls are frequently found in natural products, drugs, chiral auxiliaries, and catalysts. This work reports a new method for the palladium-catalyzed oxyalkynylation and oxyarylation of propargylic amines. The reaction is perfectly regioselective based on the in situ introduction of a hemiacetal tether derived from trifluoroacetaldehyde. cis-Selective carbo-oxygenation was achieved for terminal alkynes, whereas internal alkynes gave trans-carbo-oxygenation products. The obtained enol ethers could be easily transformed into 1,2-amino alcohols or -amino ketones using hydrogenation or hydrolysis, respectively.
