The meso-salicylaldehyde substituted BODIPY was synthesized over a sequence of steps and characterized by X-ray crystallography, mass, NMR, absorption, fluorescence and electrochemical techniques. The crystal structure showed the presence of strong intramolecular hydrogen bonding between hydroxyl and formyl groups, which induces rigidity in the BODIPY core and makes the BODIPY relatively more f...

A salicylaldehyde-based molecular sensor was synthesized in a one-step facile way and designed for visual detection of viscosity liquids.

The title compound, [Cu(2)(C(14)H(12)ClN(2)O)(2)Cl(2)], is a copper(II) dimer where the metal centres are bridged by O atoms from a 5-chloro-salicylaldehyde group. The coordination geometry of each copper(II) centre is distorted square-pyramidal, with two N atoms from a 2-ethyl-amino-pyridine group and two O atoms from a 5-chloro-salicylaldehyde group occupying the basal positions, and with a C...

In the title compound, C(17)H(21)N(3)O(3)S, the dihedral angle between the aromatic ring planes is 84.2 (2)°. The pendant ethyl groups of the -N(C(2)H(5))(2) group are disordered over two sets of positions in a 0.84 (2):0.16 (2) ratio. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, and inter-molecular N-H⋯O bonds lead to [010] chains in the crystal structure.

Herein we demonstrate for the first time that a boron promoted one-pot assembly reaction may be used to discover novel enzyme inhibitors. Inhibitors for HNE were simply assembled in excellent yields, high diastereoselectivities and IC50 up to 1.10 μM, based on components like salicylaldehyde, aryl boronic acids and amino acids. The combination of synthetic, biochemical, analytical and theoretic...

Two potentially heptadentate (N4O3) tripodal Schiff-base ligands: tris(3(salicylideneimino)propyl)amine (H3L1) and tris(3-(4'-hydroxysalicylideneimino)propyl)amine (H3L2) have been prepared and characterized by various spectroscopic methods (IR, FAB-MS, NMR). They are derived from the condensation reactions of tris(3-aminopropyl)amine (tpt), with 3 equivalents of either salicylaldehyde or the r...

known to have a coordination number of seven. Nearly all of them have the basic formulation [Ln(bidentate)3(unidentate)]. On the contrary, structurally characterized examples of a heptadentate ligand coordinating one metal ion are rare. Tris(2-aminoethyl)amine (tren) condenses with salicylaldehyde or its substituted analogs in a 1:3 molar ratio to form Schiff-bases which are potentially tribasi...

Two different classes of fluorescent dyes were prepared as a turn off/on sensor system for aldehydes. Amino derivatives of a boron dipyrromethene (BDP) fluorophore and a xanthene-derived fluorophore (rosamine) were prepared. Model compounds of their product with an aldehyde were prepared using salicylaldehyde. Both amino boron dipyrromethene and rosamine derivatives are almost non-fluorescent i...
