A STUDY OF THE PREPARATION AND REACTIONS OF THE UNUSALLY LABILE 5-METHYLOXADIAZOLOQUINAZOLIN-2-ONE

A ?2s + ?2s + ω2s cycloaddition of 4-isocyanato-2-methyl quinazoline 3-oxide leads to the title compound, 5-methyloxadiazoloquinazolin-2-one (1).Surprisingly, the weakest bond in 1 is 4-5.Rupture of this bond takes place thermally as well as with P(OR)3 leading to the isomeric, 5-methyloxadiazoloquinazolin-3-one (11).A detailed thermolytic study of 1 has given products arising from scission of the bonds 2-3, 3-4- and 4-5.The 3-4 bond is preferentially broken on photolysis of 1 in MeOH.
