Which represents the most stable conformation for cis-1-tert-butyl-4 methylcyclohexane? What is the most stable conformation of 1-tert-butyl-1-methylcyclohexane in the chair conformation? Which of the following dienes (a) (b) (c) in the figure have an s-cis conformation, and which have an...
The target product N(e)-Boc-L- L-Lysine can be prepared by using benzyl chloroformate and di-tert-butyl dicarbonate as reaction materials. Benzyl chloroformate protects the α-amino group, and di-tert-butyl dicarbonate protects the amino group. The protective group on the α-amino group is ...
Gadolinium ethoxybenzyl dimeglumine (Gd-EOB-DTPA, Primovist® in Europe and Eovist® in the USA) is a liver-specific magnetic resonance imaging contrast agent that has up to 50% hepatobiliary excretion in the normal liver. After intravenous injection, Gd-EOB-DTPA distributes into the vascular ...
The monomers were altered in such a way that they incorporated various bulky groups such as 2,5 t-butyl phenylene, trifl uoromethyl, adamantly and tri-tert-butylphenol in the polyamide main chain. The motivation for the incorporation of bulky groups in the main chain was to increase ...
