A metal-free protocol for accessing both α and δ-carboline derivatives, starting from a common indolylchalcone oxime ester precursor is reported. The reaction involves mild conditions and uses a regiodivergent approach. DDQ is used as a switching agent in selectively generating α and δ-carboline derivatives in good to moderate yields.

The Michael addition of 1-acetyl-3-indolinone to α, β-unsaturated aldehydes and ketones is described. The synthesis of a number of δ-carbolines that contain alkyl and aryl substituents in the 2 and 4 positions was realised on the basis of the resulting 1,
