o‐tolualdehyde tert‐butylimines were shown to condense with nitriles to form eneamido anion intermediates that were trapped in situ with various electrophiles, thus affording a diverse array of highly substitutedisoquinolines, many of which are difficult to access by known methods. Further substitutional diversification was achieved by modification of the work‐up conditions and by subsequent transformations.

simple metal-free approach, utilizing an imine transient directinggroup. The strategy covers a wide spectrum of reactions and (i) even highly sterically hindered C–H bonds can be borylated smoothly, (ii) despite the presence of other potential directinggroups, the reaction selectively occurs at the o-C–H bond of the benzaldehyde moiety, and (iii) natural products appended to benzaldehyde derivatives can
