| Abstract: | Reactions of 2,3-dichloroquinoxaline 1
with various acid hydrazides 2 in acetonitrile under PTC conditions give
the corresponding oxadiazinoquinoxalines 3, which on reaction with
sodium alkoxides in alcohol yielded the respective ring opened products i.e.
2-acylhydrazino-3-alkoxyquioxalines 4. The compound 4 has been also synthesised from
2-acylhydrazino-3-chloroquinoxaline 5, which is obtained by the reaction
of 1 with 2 in DMF at room temperature. |
