Near-infrared (NIR) fluorescent probes possess a characteristic molecular structure with a highly conjugated polyene or polynuclear system, thus exhibiting a long emission wavelength over 650 nm up to 900 nm. They are of increasing interest owing to

The stereoselective synthesis of mixed alkyl-aryl vicinal diamines was demonstrated by the use of 1,2-bis(2-hydroxyphenyl)-1,2-diaminoethene (hpen). A sequential addition of aryl and alkyl aldehyde to hpen gave a fused imidazolidine-dihydro-1,3-oxazi

We have synthesized and tested a new binolaldehyde compound 1, against five diamine compounds. Using 1H NMR (400 MHz) spectroscopy, stable diasteriomeric imine complexes between 1 and five diamines were formed. Chemical shift nonequivalences (up to 0

A combination of an achiral pyridoxal analogue and a chiral base has been developed for catalytic deuteration of L-alanine with inversion of stereochemistry to give deuterated D-alanine under mild conditions (neutral pD and 25 °C) without the use of

Biomimetic studies of pyridoxal and pyridoxamine models are of both fundamental and practical interest. This review examines (i) deracemization of α-amino acids with a chiral pyridoxal model, (ii) sensing of chirality of small molecules including α
