Abstract:

The synthetic opportunities furnished by organic synthesis and the inherent structure-directing possibilities of coordination complexes have been combined in the assembly of a series of layered metal-containing hybrid materials. The supramolecular assembly relies on self-complementary non-covalent interactions, and in five of the six structures presented herein, N–H···O=C hydrogen bonds between acetamide moieties on neighbouring ligands provide the primary structure-direction tool as intended. The distances between metal ions are controlled by ligand···ligand hydrogen bonds and reside within a

Abstract:

The co-crystallisation behaviour of three symmetrical dipyridylacetylacetone ligands (1,3-di(2-pyridyl)-1,3-propanedione (o-bppdH), 1,3-di(3-pyridyl)-1,3-propanedione (m-bppdH), and 1,3-di(4-pyridyl)-1,3-propanedione (p-bppdH)), with the linear halogen-bond donor 1,4-diiodotetrafluorobenzene (1,4-DITFB) has been investigated. The reaction of these components under ambient conditions in a 1 : 1 stoichiometry produced four halogen-bonded assemblies ([o-bppdH·1,4-DITFB, [m-bppdH·1,4-DITFB], [2(m-bppdH)·1,4-DITFB], and [p-bppdH·1,4-DITFB]).

Abstract:

Bond cooperativity effects, which are typical of `resonant' chains or rings of π-conjugated hydrocarbons, can also occur in hydrogen-bonded systems in the form of σ-bond and π-bond cooperativity or anticooperativity. σ-Bond cooperativity is associated with the long chains of O—H...O bonds in water and alcohols while σ-bond anticooperativity occurs when the cooperative chain is interrupted by a local defect reversing the bond polarity. π-Bond cooperativity is the driving force controlling resonance-assisted hydrogen bonds (RAHBs), while π-bond anticooperativity has never been considered so far

Abstract:

Sulfated tungstate efficiently catalyzes the cyclodehydration of 1-(2-hydroxyphenyl)-3-aryl-1,3-propanediones to flavones under solvent-free conditions. Utilization of conventional heating, simple reaction conditions, short reaction time, ease of product isolation and purification makes this manipulation very interesting from an economic and environmental perspective. Under these conditions, twelve examples were obtained with good yields (85-94%).

Abstract:

A convenient synthesis for β-(3-quinolinyl)-α-alanine (4) is presented. Condensation of 2-chloro-3-chloromethylquinoline (5) with diethyl acetamidomalonate (2) gave high yield of diethyl 2-acetylamino-2-(2-chloro-3-quinolinylmethyl)- propanedionate (6), which was dehalogenated in the presence of ammonium formate and palladium/charcoal. Diethyl 2-acetamido-2-(3-quinolinylmethyl)-malonate (3) was easily converted to the amino acid. The condensation reaction between 2 and 6 is also useful for the construction of (1H)-2,3-dihydropyrrolo[2,3-b]quinoline-2,2-bis(carboxylic acid) and pyrrolo[2,3-b]qu

Abstract:

A simple and highly efficient protocol for synthesis of flavones from 1-(2-hydroxyphenyl)-3-aryl-1,3-propanediones in presence of ZnO nanoparticles as a promoter in thermal as well as microwave irradiation under solvent-free conditions have been demonstrated. The catalyst is inexpensive, stable, can be easily recycled/reused for several cycles with consistent activity and observed almost same yield confirming the stability of the catalyst. It is believed that the present approach will become an alternative route for the conventional reactions. Because in this protocol, yield is quite high, sho
