In this study, fourteen novel indole-pyrimidine hybrids were designed and synthesized. Their chemical structures were confirmed using different spectroscopic techniques (1H NMR, 13C NMR, IR and mass). Their (E) stereochemical configuration was determined theoretically (MM2 property) and experimentally using 2D NMR technique (NOESY experiment). The prepared compounds were subjected to preliminary biological
The hydrolysis of N-p-toluoylindole and its 3-formyl derivative, at pH 8.0, are accelerated by a factor of nearly 103 by an antibody obtained against a KLH conjugate of N-p-toluensulfonylindole.
A unified method for direct C4–H halogenation of indoles has been accomplished with the assistance of anthranilic acids as suitable transient directing groups. Exclusive site selectivity (one out of five potential reactive sites) as well as good functional group tolerance was obtained to install three kinds of halogen atoms (Cl, Br and I, respectively) by using inexpensive N-halosuccinimides (NXS)
transition state for hydrolysis of a distorted amide, accelerates the hydrolysis of the corresponding amides 1 a-3 a by a factor of 10(3) at pH 8. The mechanisms of both the uncatalyzed and antibody-catalyzed reactions were studied. Between pH 8 and 12 the uncatalyzed hydrolysis of N-toluoylindoles 1 a and 3 a shows a simple first-order dependence on [OH(-)], while hydrolysis of 3 a is zeroth-order
