Abstract
A useful sequence of reaction for the synthesis of a variety of dibenzoheterocycles is described in one-pot. This synthesis involves the initial formation of dianion via deprotonation of Schiff base followed by nucleophilic attack on the suitable dielectrophiles. Products (1–9) were characterized by spectroscopic data and elemental analyses. A plausible mechanistic logic and concept utilized in the synthesis have been discussed in detail.
