|
|
|
Furoylhydroximoyl chloride 3 reacted with 2-aminopyridine, 2-aminopyrimidine. 0-aminophenol, 0-phenylenediamine and aminothiophenol to afford imidazo[1,2-a]pyridine 6, imidazo[1,2-a]pyrimidine 8, benzoxadiazine 10, nitrosobenzopyrazine 13a and nitrosobenzothiazine 13b, respectively. Isoxazoline 18 and pyrrolidino[3,4-d]isoxazoline-4,6-dione derivatives 19a and 19b obtained by the reaction of 3 with acrylonitrile and N-arylmaleimide. Hydroximoyl chloride 3 reacted with thiophenol and sodium benzenesulfinate to yield furylglyoxaloxime 16a and 16b, respectively. Hydroximoyl chloride 3 reacted also with some active methylene compound to give isoxazole derivatives 20-23, respectively.
