Abstract
PURPOSE: To prepare a heterocyclic compound useful as an intermediate for medicines and pesticides, in high yield in a simple operation advantageously, by reacting safe and easily handleable acyl Medlrm's acid or its homolog with an amino compound.
CONSTITUTION: An acyl derivative of Meldrums acid of formula I: (R1, R2, and R3 are lower alkyl groups) or its homolog is reacted with a compound of formula II: (R4 is H, alkyl, or (un)substituted phenyl group; X is -CO-,-CS-, or -SO2-), hydroxylamine (hydrochloride, sulfate, etc.) or a hydrazine of the formula R5NH NH2 (R5 is the same as R4) under heating or melting, and, if necessary, in an inert solvent, at room temperature to refluxing one to give a hetercyclic compound consisting of a compound of formula III, an isoxazole derivative of formula IV, or a pyrazole derivative of formula V. The raw material can be readily obtained by acylating Meldrum's acid according to the conventional method.
