The Chemistry of Heterocyclic Compounds, Fused Pyrimidines
B. 4-Carboxyquinazolines Isatinic acid derivatives are the best source of 4-
carboxyquinazolines. A Bischler synthesis (Ch. III, Sect. LA.) using N -acyl isatinic
acids yields 4-carboxyquinazolines33 in which the nature of the 2-substituent ...

The presence of a constant amount of isatinic acid indicated a contamination of
the added isatin. HPLC elution were plotted versus time (Figure 2). One major
compound (RT, 3.9 min) more hydrophilic than isatin and more hydrophobic than
...

The isatinic acid anion corresponding to the 4-substituted isatin is a relatively
strong conjugate base, and, therefore, more inclined to accept a proton. It
stabilises at pH 8.0 or above. The lowering of pH value below 8.0 destabilises the
isatinic ...
Under the influence of alkalis, isatine is acidified, absorbing one atom of water,
and gives rise to a new compound, isatinic acid, the formula of whose salts is
C32 H12 N2 05. Isatine, treated by ammonia, forms six or seven different bodies
...

tuted isatin is a relatively strong conjugate base, and, therefore, more inclined to
accept a proton. It stabilizes at pH 8.0 or above. The lowering of pH value below

Isatinic acid is monobasic, consequently it contains C16H12N203, H20. We can
cause this body to give up not only the atom of ready formed water, but also
another atom which is produced at the expense of the anhydrous acid. There
remains ...
