Heterocycles containing one or two atoms of oxygen are synthesized by the condensation of pyridine carboxaldehydes with ethylene glycol, 1,3-propanediol, and 3-methyl-3-buten-l-ol. When the unsaturated alcohol is used, linear acetals are formed along with the cyclic products. Pyridine and oxygen-c
A comparative study has been performed to evaluate the ability of a range of computational theories to predict the relative basicity and the Ε½ . conformations of diamine systems. Specifically, molecular mechanics MM3 , Ε½ . Ε½ . semiempirical AM1 , and ab initio HartreeαFock methods have been used in
