A scalable synthesis of the (S)-4-(tert-butyl)-2-(pyridin-2-yl)-4,5-dihydrooxazole ((S)-t-BuPyOx) ligand

Beilstein Journal of Organic Chemistry, 2013
An efficient method for the synthesis of the (S)-4-(tert-butyl)-2-(pyridin-2-yl)-4,5-dihydrooxazole ((S)-t-BuPyOx) ligand has been developed. Inconsistent yields and tedious purification in known routes to (S)-t-BuPyOx suggested the need for an efficient,

Redetermination of picolinic acid hydrochloride at 150 K

Acta Crystallographica Section E Structure Reports Online, 2007
The structure of the title compound, C6H6NO2+·Cl−, was previously determined at ambient temperature [Laurent (1965). Acta Cryst. 18, 799–806]. This redetermination at 150 K is to a far higher precision. On cooling to 150 K, the unit cell contracts most in the π–π stacking direction, b, and rather less so in the directions involving the strongly ...
