Addition of dianions of carboxylic acids to imines. Influence of the acid in the outcome of the reaction [PDF]

open access: yes, 2009
The addition of different carboxylic acids dianions to N-benzylidenebenzeneamine have been studied. The outcome of the reaction depends on the acid. Saturated ones lead to β-aminoacids with good yields and syn-selectivity whereas α,β-unsaturated ones ...

Complexes of Zinc With Picolinic and Aspartic Acids Inactivate Free Varicella-Zoster Virions

open access: yesMetal-Based Drugs, 1996
Zn(II) picolinate and aspartate, Zn(pic)2 and Zn(asp)2, have been shown to inhibit key steps of the replication of HSV-1. In the present study we describe the effect of Zn(pic)2 and Zn(asp)2 on the replication of VZV and on the infectivity of free ...

Redetermination of picolinic acid hydrochloride at 150 K

open access: yesActa 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 ...
