Discussion on the regioselectivity of aminolysis of 5-bromo-2,4- dichloro-6-methylpyrimidine in ethanole

Abstract

Crystallographic data analyses indicate that three types of prolinium cations, along with two types of hydrogen bonding, produce and stabilize the helical structure of triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. The stronger “conventional" hydrogen bonds and the less common C-H…O attractions play critical roles in generating and stabilizing the DNA-like network.
