| titleOfInvention | Preparation of heterocyclic compound |
| 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. n CONSTITUTION: An acyl derivative of Meldrums acid of formula I: (R 1 , R 2 , and R 3 are lower alkyl groups) or its homolog is reacted with a compound of formula II: (R 4 is H, alkyl, or (un)substituted phenyl group; X is -CO-,-CS-, or -SO 2 -), hydroxylamine (hydrochloride, sulfate, etc.) or a hydrazine of the formula R 5 NH NH 2 (R 5 is the same as R 4 ) 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. n COPYRIGHT: (C)1979,JPO&Japio |
