Disclosed herein is a visible light mediated cyclization of methyl (α‐naphthyl) acrylates and heteroaromatic analogues yielding substituted acenaphthenes and azaacenaphthenes. This highly functional‐group‐tolerant transformation was put to the test in an enantioselective formal synthesis of delavatine A. Mechanistic details were elucidated by DFT‐calculations revealing an unusual intramolecular H‐transfer

The palladium catalyzed hydroesterification of acenaphthylene takes place through a “hydride” mechanism, that is, through the selective cis insertion of the olefin into the palladium–hydride bond, an obvious prerequisite for the successful development of an enantioselective version of the reaction; however, a degenerate substitution equilibrium between Pd0Ln and the PdII-alkyl species, involving the inversion of the alkyl carbon, is also operative producing a detrimental effect in the enantioselectivity of the reaction.
