Current approaches to the synthesis of aromatic and heteroaromatic azamacrocycles and
their derivatives are summarized and systematized. The relationship between the structure …

New derivatives of thiacrown ethers were synthesized based on the domino reaction of 1, 5‐
bis (2‐formylphenthio)‐3‐oxapentane with ketones containing active methylene group and …

Herein we presented the synthesis of azacrownophanes containing tetrahydropyridine or
piperidone rings. The multicomponent reactions were performed and afforded …

Abstract Reactions of aza-14-crown-4 incorporating 4-oxopiperidine-3-carboxylate moiety

Multicomponent reactions (MCR) are power tools in modern organic synthesis. These
reactions have many advantages over single component reactions, including saving time …

New derivatives of crown compounds were successfully prepared via multicomponent
reactions of a thia‐podand, an β‐keto ester and ammonium acetate based on modifications …

Six novel phane-structured diazacrowns containing γ-piperidone and pyridine rings were
