Design of branched and chiral solvatochromic probes: Toward quantifying polarity gradients in dendritic macromolecules

(Chemical Equation Presented) A pair of chiral, branched monomer building blocks, consisting of a solvatochromic probe and a spectroscopically inactive volume dummy, has been developed. The probe can selectively be excited, and its fluorescence characteristics provide information about local polarity. Incorporation of these monomers into high-generation polyester dendrimers should enable a detailed investigation of the polarity/density profile in dendritic architectures and ultimately allow for the realization of energy gradients from one chromophore building block only.

Phase-transfer-catalyzed asymmetric Michael reaction using newly-prepared chiral quaternary ammonium salts derived from L-tartrate

The catalytic asymmetric Michael reaction of a glycine Schiff base was demonstrated using new PTCs and moderate to good ee's were achieved (up to 77% ee).
