Role of the gauche effect and local 1,3-dipole-dipole interactions in stabilizing an unusual conformation of tartarodinitriles
{{output}}
This paper reports the synthesis, X-ray and NMR investigations of chiral and meso dinitriles of tartaric acid (tartarodinitriles) and their O,O'-diacetyl and O,O'-dibenzoyl derivatives. While in chiral tartaric acid its esters and NH amides the four-atom carbo... ...
