N-heterocycles, namely 1,2,4-oxadiazoles and 2,6 disubstituted pyrimidin-4-ones, have been synthesised in one pot via carboxamidation of amidines with aryl carboxylic acids and aryl propargylic acids under metal-free conditions.
A pyrimidine compound represented by below formula (I) has excellent control activity against pests and is useful as an active ingredient of a pest controlling agent.
A method of obtaining information about a chemically active area of a target molecule, for example for drug discovery, comprising:
providing a set of substantially rigid chemical gauges;
reacting said target with a plurality of gauges of said set of gauges;
assaying a binding of said gauges with said target to obtain a plurality of assay results; and
analyzing said assay results to obtain information about said chemically active area.
