Hu, Deqing published the artcileBiaryl and atropisomeric biaryl aldehyde synthesis by one-step, metal-free benzannulation of aryl enals and propiolates, Formula: C7H13NO2, the publication is Green Chemistry (2020), 22(20), 6773-6777, database is CAplus.
A new method involving the benzannulation of aromatic enals ArCH=CHCHO (Ar = C6H5, 2-furyl, 1-naphthyl, etc.) and two alkyl propiolate mols. CHCC(O)2R (R = Me, Et, t-Bu) has been developed as a powerful route to biaryl aldehydes I simply via the promotion of di-Me 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 I. An enamine activation based on the aza-Michael addition of di-Me amine to the propiolate and the amine elimination-based generation of cyclohexadiene intermediate constitute the major factors enabling the titled reactions.
