Easy as one, two, three. Highly substituted anilines are accessible with unprecedented efficiency from the three-component-coupling reaction of O-benzyl carbamate, aldehydes, and dienophiles followed by a new domino aromatization/deprotection reaction inv
On the photophysical properties of new luminol derivatives and their synthetic phthalimide precursors

The photophysical properties of a series of structurally related 4-aminophthalimides and the corresponding 5-aminophthalic hydrazides (luminols) are reported. Absorption, steady-state, and time-resolved fluorescence spectra of luminols exhibited substitution, solvent, and pH dependence. Singlet lifetimes have been determined by time-resolved laser flash spectroscopy. UV spectra in gas phase and DMSO solution were calculated by TD-DFT which revealed the existence of two low-energy excited singlet states with strong pH-sensitivity.

A new general synthesis of substituted luminols (5-amino-2,3- dihydrophthalazine-1,4-diones) is presented. Diversely substituted luminol derivatives can be synthesized in three steps. The products are of interest as new materials, which exhibit chemiluminescence.
