Face-to-face stacking in sulfonamide based bis-ethylene bridged heteroaromatic dimers

Four sulfonamide based bis-ethylene bridged heteroaromatic dimers were synthesized for analysis of their structural and conformational properties. Interestingly, all models showed intramolecular offset face-to-face stacking between the tosyl group and heteroaromatic system in their solid state conformations. 1H NMR of the solutions revealed that the conformations were not far off from the solid state stacked geometry. However, gaseous state optimizations of different conformers divulged that the crystal structures were the lowest energy conformers.

A new receptor with a FRET based fluorescence response for selective recognition of fumaric and maleic acids in aqueous medium

Preferential binding of a new reagent to fumaric acid could be utilized for its estimation in aqueous medium and in commercial fruit juice.

Synthesis of Selectively Protected Polyaza Macrocycles

A general route to selectively protected polyaza macrocycles has been developed using a mixture of diethylphosphoryl and tosyl groups for protection of linear chain polyamines.Condensation of N-(diethoxyphosphoryl)-N',N''-ditosyldiethylenetriamine (1a), N

N-(ω-TOSYLOXYALKYL)PHTHALIMIDES AS REACTIVE GENERAL SYNTHONS FOR INTRODUCING ALKYLAMINO GROUPS AND THEIR APPLICATION FOR THE "SELF-PROLIFERATIVE" SYNTHESIS OF OPEN-CHAIN POLYAMINES

New synthetic routes to N-(ω-tosyloxyalkyl)phthalimides (2) were developed and the synthetic utility of 2 as alkylating reagents was exemplified in the open-chain polyamine synthesis involving the "self-proliferative" process.
