A highly selective and sensitive Al 3+ and Cu 2+ ion receptor (4-(dimethylamino)-2′-
hydroxychalcone) was designed, synthesized, and characterized via standard techniques …

A series of novel azacalix [2] arene [2] pyrimidines were synthesized, and evaluated for their
antiproliferative activities against A549, MCF7, SH-SY5Y and CNE human cancer cell lines …

Tetraamino-tetranitro-azacalixarene 5 is at the crossroad of two different families of
compounds depending on the conditions and the agent used to reduce the NO2 groups:(1) …

Reaction of the f-element complexes ThCl4 (THF) 3, Cp* 2Sm (μ-Cl) 2MgCl (THF) 2, NdCl3,
Cp* 2UMe2, and Cp* 2ZrMe2 with an excess of catecholborane (HBCat) yields macrocyclic …

Reaction of tert-butyl 3, 5-diaminobenzoate with cyanuric chloride gave triazine-based
macrocycle 1 in 44.3% yield, which was characterized by 1H and 13C NMR spectroscopy …

The enantiomeric excess is a key parameter for chemical and pharmaceutical industries for

Abstract Six tetraaza [1.1. 1.1] cyclophane derivatives bearing peripheral amide groups were
prepared according to two distinct synthetic strategies that depend on the connection pattern …

Polyguanamine derivatives having cyclic moieties constituted by two phenyl and two triazine
rings have been synthesized, and a supramolecular organization based on their multiple …

Template-induced synthetic routes for azacalix [n](2, 6) pyridines (n= 3, 4) have been
elaborated. The proton and nickel ion served as the efficient template for the cyclization …
