Saccharinyl benzole acid azides 2a-c were used to synthesize a number of noncondensed heterocyclic systems. Thus azides 2a or 2c reacted with glycine to give 1,3-oxazolin-5-one derivatives 3a and 3b. However azide 2b reacted to give diaryl urea derivative which was easily cyclized to give imidazol -2,5- dione (6). Also azides 2a-c reacted with glycolic acid to give 1,3-oxazolin -2,5-dione derivatives (7a-c) and with aroyl hydrazines to give the corresponding hydrazides (8a-f) which were cyclized to 1,3,5-oxadiazole derivatives (9a-f).
