Fluorophore‐Functionalized and Top‐Covered Resorcin[4]arene Cavitands
Israel Journal of Chemistry, 2011AbstractThis review describes our recent developments in the field of resorcin[4]arene cavitands. We present the syntheses of cavitands bearing pyrene, anthracene, and BODIPY dyes as fluorophores on the cavitand walls. These systems have been used to examine the conformational switching process between the closed vase and the open kite forms that are ...

Synthesis of Amino and Ammonium Resorcin[4]arenes as Potential Receptors
Synthesis, 2008Starting from the tetrabromide 1A (cone conformation) a number of resorcin[4]arene derivatives ( 3A, 4A, 5A, 6A) containing an amino function in the side chains have been prepared. Preliminary investigations, including UV, NMR, and MS analyses, of mixtures of the resorcinarene and its potential guests, such as metal cations or amino acids, evidenced ...

Cyclochiral resorcin[4]arenes as effective enantioselectors in the gas phase
Journal of Mass Spectrometry, 2012The effect of cyclochirality of rccc‐2,8,14,20‐tetra‐n‐decyl‐4,10,16,22‐tetra‐O‐methylresorcin[4]arene (C) on the enantiodiscrimination of a number of chiral bidentate and tridentate aromatic and aliphatic biomolecules (G) has been investigated by nano‐electrospray ionization (nano‐ESI)‐Fourier transform ion cyclotron resonance mass spectrometry.

Abstract The cyclocondensation of 1,3-dialkoxybenzenes with 1,3,5-trioxane was catalyzed by Sc(OTf)3 to produce resorcin[4]arene octaalkyl ethers as the major products. In addition, ‘confused’ resorcin[4]arene octaalkyl ethers bearing one alkoxy group at the intra-annular position were obtained as the minor products.

Chiral Recognition by Resorcin[4]arene Receptors: Intrinsic Kinetics and Dynamics
Chemistry – A European Journal, 2004AbstractMolecular recognition of representative amino acids (A) by a chiral amido[4]resorcinarene receptor (1L) was investigated in the gas phase by ESI‐FT‐ICR mass spectrometry. The ligand displacement reaction between noncovalent diastereomeric [1L⋅H⋅A]+ complexes and the 2‐aminobutane enantiomers (B) exhibits a distinct enantioselectivity with ...

Cyclochiral conformers of resorcin[4]arenes stabilized by hydrogen bonds
Organic & Biomolecular Chemistry, 2007Cyclochiral resorcinarenes, that maintain their cyclochirality by means of hydrogen bonds, were synthesized by a sequence of reactions involving the Mannich reaction, removal of the N,O-acetal bridge and subsequent N-substitution with an RCO group. During this study it was found that ethyl nitroacetate is a mild and very efficient agent for N,O-acetal ...

Structural conformers of symmetry substituted resorcin[4]arenes
Journal of Molecular Structure, 2003Abstract Methylresorcin[4]arenes in the C2h and C4v symmetrical chair and crown conformers, and resorcin[4]arene in the C2v symmetrical boat conformation have been synthesized from the typical one-pot acid-catalyzed reaction and structurally characterized.

Synthesis of Methylene-Bridged Resorcin[4]arene Dimers
Synthetic Communications, 2015AbstractMethylene-bridged resorcin[4]arene dimers were synthesized by the Sc(OTf)3-catalyzed hydroxymethylation of partially acetylated resorcin[4]arenes, and their preliminary complexation properties with tetraethylammonium ion were examined in CD3OD by 1H NMR spectroscopy.
