Abstract

In this tandem reaction the carbon-carbon triple bond of an alkyne is catalytically cleaved in association with aldehyde, al-kene, and H2O under catalyst mixtures of Rh(I), 2-amino-3-picoline, primary amine, and acid. The reaction starts with chelation-assisted hydroacylation of the alkyne with an aldehyde. The retro-Mannich-type fragmentation of the resulting ,α,β-unsaturated ketimine by an amine and acid affords a ketimine and an aldimine, which is trapped by an alkene and give ketones after hydrolysis.
