## Abstract This study represents a facile synthesis of building blocks (**1–3**) of crown ethers and amine precoursers (**4a‐d**). The study also involves synthesis of mono and dibenzo __N, N__‐disubstituted diaza 18‐crown‐6 derivatives with high yield without chromatographic purification and high
