Calixarene alpha-ketoacetylenes: versatile platforms for reaction with hydrazine nucleophile

“…Alkynyl derivatives of (thia)calixarenes have been extensively exploited for click chemistry and are readily accessible in a range of conformations. 40 …”

Template Synthesis of Tetrakis-triazolylthiacalix[4]arene in the Cone Conformation and Supramolecular Structure of Its Hexanuclear Complex with Ag(I)

“…Recently, we have reported the synthesis of tetrakis(propargyloxy)thiacalix [4]arene [13] (1), in 1,3-alternate conformation. The latter was obtained by alkylation of the lower rim by propargyl bromide in acetone in presence of Cs 2 CO 3 .…”

“…1 was obtained according to the already reported procedure. [13] The NMR spectra were recorded in CDCl 3 or DMSOd 6 solvents on Bruker spectrometer Avance 600. Bruker Vector 22 Fourier spectrometer was used to record IR spectra in the wavenumber range of 400-4000 cm -1 in KBr pellets or nujol.…”

Bifunctional Derivatives of (Thia)calix[4]-arenes with Terminal Double and Triple Bonds: Synthesis and Azide-Alkyne Click Reactions

“…Так, двойные связи могут быть легко функционализированы реакцией радикаль-ного присоединения тиолов, [5,6] а тройные -путем медь(I)-катализируемого циклоприсоединения 1,3-диполей. [7][8][9][10][11] Несмотря на большое разнообразие исследований в химии каликсаренов и их тиа-аналогов, публикации, где были бы получены бифункциональные каликсарены, содержащие двойные и тройные терминальные связи, отсутствуют.…”
