Mild Microwave-Assisted Synthesis of Dipyrromethanes and Their Analogues
摘要:
The Mannich reaction between pyrroles or indoles and Eschenmoser's salt (dimethylmethylideneammonium iodide) forms N,N-dimethylamino-methylated derivatives in good to excellent yields. The reaction is highly regioselective, and for pyrroles both 2- and 3-substituted derivatives could be obtained. The N,N-dimethylaminomethylpyrroles and indoles underwent substitution with pyrrole under microwave irradiation, affording the appropriate dipyrromethanes, N-confused, and indolo-dipyrromethanes in moderate to excellent overall yield.
A class of novel 1-indole-3-acetamides represented by the formula; ##STR1## is disclosed together with the use of such indole compounds for inhibiting sPLA.sub.2 mediated release of fatty acids.
A class of novel 1H-indole-3-acetamides is disclosed together with the use of such indole compounds for inhibiting sPLA2 mediated release of fatty acids for treatment of conditions such as septic shock.
