Biaryl and atropisomeric biaryl aldehyde synthesis by one-step, metal-free benzannulation of aryl enals and propiolates

A new method involving the benzannulation of aromatic enals and two alkyl propiolate molecules has been developed as a powerful route to biaryl aldehydes simply via the promotion of dimethyl amine. The benzannulation process in the absence of an oxidant additive tolerates successfully the formyl group in the enal component, leading to a straightforward one-step synthesis of biaryl and atropisomeric aldehydes. An enamine activation based on the aza-Michael addition of dimethyl amine to the propiolate and the amine elimination-based generation of cyclohexadiene intermediate constitute the major factors enabling the titled reactions.

Paragraph 0027-0044, (2021/02/10)
The invention relates to a preparation method of ethyl 3-(N,N-dimethylamino)acrylate, which comprises the following steps: carrying out heating reaction on formic acid, ethyl acetate and dimethylamineto obtain ethyl 3-(N,N-dimethylamino)acrylate and water. The preparation method of the ethyl 3-(N,N-dimethylamino)acrylate is short in reaction route, high in yield and purity and low in safety risk.

In the presence of Au nanoparticles supported on manganese oxide OMS-2 (Au/OMS-2), various kinds of β-heteroatom-substituted α,β-unsaturated ketones (heteroatom = N, O, S) can be synthesized through α,β-dehydrogenation of the corresponding saturated ketones using O2 (in air) as the oxidant. The catalysis of Au/OMS-2 is truly heterogeneous, and the catalyst can be reused.
