Facile synthesis of mono and dibenzo <i>N</i>,<i>N</i>'‐disubstituted diaza 18‐crown‐6 derivatives

Abstract

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 vacuum distillation. The complex ability of host the ethers was evaluated in terms of structural modification.
