The pyridine-ring hydroxylation step is one of main initial steps in the degradation of pyridines [4]. Our analyses of the accumulated metabolites from 4-aminopyridine and the growth substrate specificity suggested that 4-aminopyridine was converted to 4-amino-3-hydroxypyridine and 3,4-dihydroxypyrid...

N absorption in the IR spectrum,i.e.1560–1590cm−1. In the partially reduced (oxadiazoline) ring the Δ2double bondappears at 1550–1565cm−1and the NH bands at 3320 and 3220–3250cm−1. In an amino derivative, 5-amino-3-phenyl-1,2,4-oxadiazole, the C ...
4). In this state, the amino-nitrogen is bonded to one of the Si atoms of a Si–Si dimer, while all three N–H bonds remain intact. The energy gain relative to the starting point (state I in Fig. 4) amounts to −37.9 kcal mol−1. The next step consists of the simultaneous...
